File Under: That Had To Hurt Comin' Out

I was sent this story about a California wildlife rehabber who found an injured hawk:

A hawk was found dead along a California highway with the claw of a songbird protruding from its chest.

It's not clear, however, if the partially digested meal, one claw somehow managing to get back out from a terribly wrong location, had anything to do with the hawk's death.

On the evening of Sunday, March 30, Julia Di Sieno of the Animal Rescue Team in California noticed the dead sharp-shinned hawk (Accipiter striatus) while driving a sick night heron to the Solvang Veterinary Hospital. Sharp-shinned hawks are birds of prey and considered stellar hunters. They are the smallest hawks that reside in the United States and Canada.

"So I did a U-turn, put on my gloves and picked the bird up, and immediately rushed him to the vet where he died in my hands," Di Sieno told LiveScience. "Upon examination, we noticed that there was a small bird foot out of its chest."

A pouch in the hawk's chest area called the crop had ripped open and the songbird, which had been a meal for the hawk, was spilling out. You can see this in a larger version of the above photo here. There is also another angle of the hawk here.

"We removed a good portion of this bird [the songbird], which was partially digested," Di Sieno said by telephone yesterday. The hawk had apparently just finished downing what might have been a sparrow, she said. "He [the dead hawk] even still had down feathers and meat on his beak."

However, Di Sieno said she is not sure how the hawk died or what caused its crop to burst open.

I'm not sure what happened. It the larger versions of the photos, the head looks really flat and more like a Cooper's hawk than a sharp-shinned--but the photos are at odd and unnatural angles. Also, the leg looks like a blackbird leg. Either way, I don't think that the prey ripped it's way out. Sharp-shins and Cooper's typically do not swallow prey whole--they are smaller and they rip it apart. I doubt whatever bird it was would have had a chance to claw it's way out of the crop. My guess is that when the hawk was hit by a car, the impact or some part of the vehicle cause the very full crop to get ripped open. But we don't know for sure and it makes for some interesting conjecture.

Speaking of bird feet undigested...

I found some interesting excrement at Carpenter Nature Center yesterday! It looks like mammal poop and that the mammal had eaten a large bird. Do you see the long bird toes in the above photo?

This chunk had shafts from feathers in it. The bird wasn't white, but the shafts got bleached as they were worked through a digestive tract.

The toes were just fascinating. I'm guessing that they are pheasant toes, but turkey is a possibility--both can be found at Carpenter. While I was taking photos I could hear a pheasant giving its old rusty car horn call not too far away. Still there are many questions: What sort of mammal is this from? Red fox? Gray fox? Coyote? Was it a turkey or pheasant? And how much did it hurt to have those bird claws coming through the back door?

Red-tailed Hawk vs Snake

My goodness, the Holy Crap factor is majorly spiking this week!

Thanks to Jennifer who alerted me to a link of photos that her mother took of a young red-tailed hawk that tried to get a snake and things went a bit wonky. Click here to view the photos. There are three photos of the hawk in an awkward position--don't worry, the hawk gets away. Although, if snakes ook you out, you may not want to follow the link.

This is a good example of how young raptors have to learn some hard lessons on not only what to hunt, but how to hunt.

Loves Me Some Minimum Maintenance Roads

Oh, the places we took this bus on our field trip!

Saturday in Nebraska we went to explore other birding areas. We drove by Funk Waterfowl Production Area which in the past few years hasn't been all that great because the cattails had grown up and hidden the ducks. But the powers that be had improved the area for wildlife viewing and it would have been perfect for our field trip--if the water had not been frozen--doh!

So we headed south for Harlan Reservoir. You can take one of the main highways, but we opted to take some minimum maintenance roads towards our destination instead. These barely maintained roads have produced some of our best birding and wildlife opportunities in the past. This time we saw came across a prairie falcon (the blurry bird above). The best part was that this falcon flew right over our group so that we got a chance to see its black armpits (a distinguishing characteristic).

One of the challenges with birding Harlan Reservoir is that you are not allowed to stop your vehicle at some of the best places to watch for waterfowl. This was near the town of Alma, that's mostly cackling geese and greater-white fronted geese in there.

We were happy to see so many geese. One of the volunteers at Rowe Sanctuary said that there wasn't much at Harlan the day before, just some diving ducks. We decided to drive the length of the lake and headed east. We found tons of robins, bluebirds, rough-legged hawks, bald eagles and gulls.

There were quite a few redhead ducks and I took an opportunity to try and figure out my mojo with my new digiscoping camera. While I was photographing the ducks, I noticed a strange sound. I had a tough time trying to determine if it was animal or mechanical. When we scanned the other side of the lake with my scope, we could see thousands of gulls, but it didn't quite sound like a flock of gulls. I decided that it was some sort of farm machinery and didn't give it much thought.

We continued driving and stopped at Republican City to have lunch at the prairie dog town--always a crowd pleaser.

I noticed a new addition this year to the prairie dog town. See the large stick nest in the above photo? Let's look through the scope and see who is nesting inside:

There we see a red-tailed hawk head. What smart hawks...and what unfortunate neighbors for the prairie dogs! Ah well, that's the food chain for you. Amber and I had birded here before, but Stan had not. We told him that if we went a few blocks away we had a pretty good chance of finding a great horned owl nest.

Sure enough, there it was. It's so weird to me that Amber and I know this area fairly well just by birding here one a year for the last several years. I think the red-tails switch nests with the great horneds from year to year. I wonder if next year the owls will be in the nest over the prairie dog town?

Even still, a red-tail right over the town and a great horned a mere few blocks away...it's a good thing prairie dogs breed like...prairie dogs.

As we continued around the reservoir we found this rather cooperative hawk in a little marina community. It had such a tiny little head I almost thought it was some weird dark morph broad-winged hawk, but it was a red-tailed hawk. Now we just had to figure out what type of red-tail. It's a dark morph red-tail, but is it just a dark morph or is a dark morph Harlan's red-tailed hawk? It had some white on the chest...

It had some what on the scapulars, and no red on the tail. The striping looks like the striping you would see on an immature red-tail. We came to the conclusion that is was an immature dark morph Harlan's red-tailed hawk. And when I checked my Wheeler books at home that seems to support the id, but if anyone cares to add their two cents worth, please feel free. We don't get too many of this type of red-tail in Minnesota.

As we worked our way around the lake, I told Stan to stop the bus and let me out. I looked at the lake and asked, "Is that ice?" If you look in the distance of the lake, you can see a long line of white. I looked through my binoculars. It wasn't ice. It was all snow geese. I felt kind of like Sam Neil's character in Jurassic Park when they first saw the dinosaurs. We had seen strings and strings of snow geese flying over all day and didn't realize they were heading towards Harlan. We decided to drive closer.

We kept taking minimum maintenance roads to see if we could get closer and we finally found a road that let out on a hill. We stopped to see if we could get out and get a clear view of all the snow geese.

I got to the top of the hill, I saw this view to my left...

And this view to my right. The snow geese just went on and on and on and on. We estimated the flock to be a mile wide and two miles wide. The sound was unbelievable and remember how I said that I heard some unidentifiable sound earlier? I now realized that I had heard the ginormous flock of snow geese.

More still came in and the flock seemed to be in a constant state of flux, rearranging itself on the water. When we later told some of the volunteers at Rowe Sanctuary they said that the day before the lake was devoid of geese and that this was the third round of snow geese to come through on the reservoir--wow.

Here is our field trip group in front of the geese. Nebraska is known for its cranes, but in some ways the geese are even more spectacular. I wonder how many Ross's geese were mixed into that flock? As amazing as the geese were to watch, we still needed to get back to our crane blind and had to keep going.

Talk about your roads less traveled! We started to go off map at this point. We had an idea of where we were but didn't know for sure. Some of the road zigged and zagged but we felt that if we went on, we would at some point reach the other end of the reservoir and a major highway to get us back to Kearney. I think we made a couple of people nervous with our exploratory ways, but Stan whipped out his iPhone and we found exactly what road we were on and were able to figure out an alternate route when the road became too muddy to continue.

One of the great things about traveling with Stan is that he knows a lot about all sorts of stuff and he is easy to egg on. My favorite things to do on a trip with him is point out a hole and tell him to stick his hand in there...sometimes he sticks his whole body! Most of the time he can id it, I think this hole was some sort of fox.

We continued to find all sorts of gems like this opossum. We also found pheasant and a flock of about 50 wild turkeys. We finally made it back onto an actual road and Stan I noticed that the signs telling use the miles to the next town specified that they were in Nebraska.

Then we passed this welcome to Nebraska sign. Somehow we had taken the minimum maintenance roads into Kansas. Who knew?

Then we passed a speed limit sign and saw this bird--can you tell what it is? If not, no worries, it was most cooperative. We pulled ahead and got out to put the scope and cameras on it.

Check it out--an owl on speed! Seriously, this is a short-eared owl perched on a sign. Its back was to us and then it turned it After we got a good long look, we loaded back into the bus and continued on our way, it took off and we got to watch its bouncy flight over the fields.

What an awesome day of birding! I think its one of the best I have ever had in Nebraska. And to give you a hint of what all those snow geese sounded like, here is a mini video that I took:

Bald Eagle Attacks Sandhill Crane

The photos in this blog entry are from Stan Tekiela and Amber Burnette.

This year's trip to Nebraska was just chock full of "Holy Crap" moments. I mean, the common crane (in the above photo) that we saw within thirty minutes of arrival to the area after driving all day was almost too much to hope for. I just found out that it's on the American Birding Association Blog and is classified as a Code 4 Bird (Casual--Species not recorded annually in the ABA Checklist Area, but with six or more total records—including three or more in the past 30 years—reflecting some pattern of occurrence). As a field trip leader you kind of wonder how you will top a sighting like that for the rest of the weekend--but top it, we did!

The following documented behavior is the type of stuff that a girl like me reads about in magazines and wonders if I'll ever have a chance to witness in real life. Again, I want to thank Stan and Amber for letting me use their photos in the blog to share it with you. Click on the photos if you wish to see the larger version.

We were watching a group of cranes forage in a field when we noticed something was spooking them and causing them to fly off. I was in the bus with half the group and Amber and Stan were outside with the rest getting shots of cranes in flight.

That's when we all noticed an adult bald eagle in hot pursuit of one of the cranes. Somehow the eagle had managed to get one crane separated from the flock. I started shouting, "It's going for the crane, it's going for the crane, it's going for the crane!" I wondered if the others outside the bus noticed, but Amber's enthusiastic yelling told me they had. Everyone was shouting on the bus, it was like an intense football game but the crowd was unsure of which team to root for--we all loved eagles and we all loved cranes (I think it's a safe assumption that for Raptor Center alums like Amber and me--we were on Team Eagle).

The bald eagle closed the gap in such a short amount of time, it pumped its wings hard and was soon on top of the crane. It flew past the crane just a little, dove at it and missed.
Here is the eagle making a second attack.The sandhill crane breaks free and starts to drop.

The eagle makes a quick grab a second time.

The eagle has the crane in its talsons and is flying while carrying the crane upside down, wings open!

The bald eagle is holding the sandhill crane for one or two seconds before...

The eagle lost its grip and the crane starts to fly away with the eagle coming after it.
The eagle gives one last chase before breaking off from the crane. What was interesting to me was that the crane and the eagle ended up flying right over our bus. As the crane flew over, the eagle appeared to slow and change direction. I'm left with so many questions from this encounter. Did the eagle not want to fly over humans? Did the crane luck out or fly over us on purpose? We did not see where either bird ended up, but did the eagle make a wide circle and wait out the exhausted crane? Did the crane fly away in its weakened state and become coyote chow? How deep did the talons get?

Out of all the sandhill cranes that took off, why that one bird? Did the eagle see something different or was it just that the crane foolishly went away from the safety of the flock? This was an adult eagle--has it killed a crane successfully before?

Such a cool encounter and yet so many questions unanswered.

Butt Load Of Snow Geese

I'm doing another interview on Talk Shoe, this time with a show called Conscious Living on Wednesday. It will be interesting to see if there are the same naughty forum questions as the other show I was on. Then I'll know if it was me bringing them out or just a weird one time thing. If you're interested in listening, go to the Talk Shoe site on Wednesday at 4pm Eastern Time.

This was a massive flock of snow geese that we found on Friday just driving around Nebraska. It's interesting that the focus of the Platte River birding in Nebraska is the sandhill crane, but the sheer numbers of snow geese are more intriguing to me. When Stan asked about doing a field trip to Nebraska through his nature center, I suggested early March. There may be fewer cranes, but enormous amounts of snow geese. And really, the numbers for both are still pretty amazing--60,000 sandhill cranes, 2 million snow geese.

I think this is one of my favorite photos from the trip. This is just a long, long line of snow geese. As cool as this is, it may be cause for environmental concern. According to Birds of North America Online the current estimates of the snow goose population is between 5 and 6 million, a number that may be environmentally unsustainable. When snow geese return to their breeding grounds, they pretty much eat the crap out of the habitat which in the long term could mean that they eat away the habitat so quickly that it won't recover for future breeding seasons causing a crash not only in their population but other species like sandpipers and phalaropes. Despite all of that, it's still pretty overwhelming to witness.

Below is a video of the above flock flying over our heads. You can hear Stan, my buddy Amber and myself giggling like fools. Non Birding Bill says it sounds like we are high.

Common Crane In Nebraska

Below is the photo of the common crane that we saw within 30 minutes of arriving to Rowe Sanctuary in Nebraska on Thursday night. This photo was taken by Stan Tekiela:

I can't believe our group saw such a rare bird on our trip! I'm also happy to report that others have seen the crane, here is an email from Linda Brown that was posted on NEBirds and has detailed directions for all you big year people who are wanting to go see it:


This morning we followed directions from Sharon Stiteler and Amber Burnett who are part of the Minnesota group of 10 who saw the common crane on Thursday, we drove to the spot after taking in the sunrise at the Gibbon Bridge viewing platform. As we scanned the flock Paul Johnsgard invited us to look at the pale whitish crane about twenty feet in from the west side of the flock. Sure enough I could see the black marking with my naked eye! It helped that all the birds were alert and looking at us so all heads were up and facing us. We put the scope on it and the following persons confirmed the sighting:

Paul Johnsgard, Josef Kren, Jackie Canterbury, Fujiyo Koizumi, Michelle Johnson, Randy Yeager and Linda R. Brown.

Josef, Paul and I drove back so we could give you good directions to the field where it was spotted two days in a row. (I have now been by the field four times in two days and only saw it once. There are two young eagles in the area keeping the flock of sandhills flighty. So, I wish you lots of good luck!)

The GIS coordinates for the crane field (from the road) are 40 degrees,41'940, 098 degrees,46'214. The abandoned eagle nest is at 40 degrees 41'940, 090 degrees,46'648.

1.Directions from Shelton Exit off I-80. Driving directions from Interstate 80, Exit 291, the Shelton exit. Drive south 1.5 miles. The crane field is 1.5 miles west of the Shelton Rd 24th Rd intersection (The field is on 24th-the road going west). The cranes were on the north side of the road. For reference: There is an abandoned eagle nest on the south side of the road 1.9 miles west from the intersection of Shelton Rd and 24th.

2. Directions from Gibbon Exit south off of I-80. Paul wrote out directions from the Gibbon Bridge Crane Viewing Platform. (This large platform is located on about the 5th Platte River channel bridge south of the Gibbon exit off of I-80. This viewing platform is accessed from Elm Island Rd which is the road directly south of the bridge. To see the common crane, drive east of Elm Island Rd to Sodtown Rd. North on Sodtown Rd to 17th, east to Sioux, north to 24th, then east to crane field on north of road. The crane field is 0.4mile east beyond the abandoned eagle nest on the south side of the road.

Coming Out Of The Fever Dreams

First, the caption contest will be decided by tomorrow morning--perhaps we'll pick the winner at Birds and Beers tonight?

Second--I love my readers. I love that you teach me something new all the time. How on earth would I have learned about a website dedicated to Feral Children? Why is that not a show on The Learning Channel?

Third, I totally thought I had a perfect blog entry the other day about a pair of cardinals that were doing a mating display in my apartment and checking out an empty onion bag on my couch as a potential nest site. I even got incredibly excited when Cinnamon hopped up next to the onion bag and the male cardinal tried to puff up and drive her off, but she tried to nibble his tail...then I woke up to blog it and then realized that wow, that was some powerful cold medicine.

Fourth and speaking of fever dreams, I DID NOT TAKE THE FOLLOWING PHOTOS, but they are making the rounds in the email inboxes, so if you haven't seen them check out this great gray owl (I think that was seen Montana, I have no idea if it is recent):

If you you know who took these photo, let me know--I'd love to give them their props. It's a partially albino great gray owl...although, I don't think we're supposed to call them partially albinos anymore, according to Birding I think we are supposed to call this partial amelanism (because you know, ornithologists like to make things simple for the general public).

Shnifty bird.

UPDATE: WE KNOW WHO TOOK THE PHOTOS! Thanks to knowledgeable blog readers we now know that the photos were taken by Cheryl Farmer in Montana and you can read more about this bird at the Prairie Ice Blog (which looks like a cool photography blog). Thanks, John!

Lawrence's Warbler?

As if fall warblers weren't already tricky to identify! Here comes a whopper.

All the photos in this blog entry were taken by bird bander Mary Messerli. She and Robert Fashingbauer were banding birds near Willow River State Park in Wisconsin on August 15, 2007 when they banded these two unusual warblers. Take a look at this:

At first glance this looks like a golden-winged warbler, however it has way too much yellow. If some of you are jumping to a hybrid conclusion, you are right. Sometimes golden-winged warblers will hybridize with blue-winged warblers.

When a golden-winged warbler mates with a blue-winged warbler, you usually get a hybrid called a Brewster's warbler. This bird doesn't look anything like a Brewster's. It has the masking of a golden-winged, but the yellow wash of the blue-winged warblers. This bird is a backcross--one of it's parents was a Brewster's and the other was either a true golden-winged warbler or true blue-winged warbler. When this happens you get another type of hybrid called a Lawrence's warbler. Confused yet? Were you able to follow that? Well, hold onto your hat, it gets even trickier:

That same day, those banders caught this bird--another hybrid. Oy! The banders said that this bird had characteristics of being a hatch year bird (it came out of the egg this year) the bird above had characteristics of being an after hatch year bird (at least a year old). But really, it's hard enough to identify hybrids and even harder to age and sex them. I think this is another Lawrence's warbler backcross (a Brewster's hybrid that bred with either a true golden-winged or blue-winged warbler). The banders felt that this bird is of unknown sex, but with the pale mask, I think it is reminiscent of a female golden-winged warbler, so I'd be willing to go out on a limb and call this female.

I nipped over to BNA Online to see what they had to say about hybrids and found this:

"Molecular analyses of hybridization indicate that Blue-wing mtDNA introgresses asymmetrically and perhaps rapidly into Golden-wing phenotypes without comparable reverse introgression and footprinting of Golden-wing mtDNA into replacement Blue-wing populations."

Holy crap, I though Pyle was hard enough to read. Basically, (I think) this is saying is that all this hybridizing and backcrossing can result in fewer golden-winged warblers and more blue-winged warblers. The hybrids and the backcrosses end up in future generations breeding into blue-winged warblers.
