It's a crossbill winter!

Here in Cincinnati we're excited because crossbills have dropped down from the north for a winter visit (and it's not even winter yet). Both Red and White-winged Crossbills are being reported daily at local cemeteries, so since Matty was off school Wednesday, we headed up to Miami Cemetery to see what we could see...

A White-winged Crossbill was waiting for us when we got out of the car! 

We didn't even have to look for the birds. As soon as we stepped out of the Jeep, three White-winged Crossbills flew in the huge Eastern Hemlock tree right next to us. Their chittery flight chatter gave them away, and we quickly focused in on them with binocs. This was a life bird for Matty, so he studied them carefully. "Wow! You really can see their crossed bills!" was the first thing out of his mouth. "I know..." followed out of mine. We watched them in silence as they moved from cone to cone, separating the bracts and extracting the seeds with their tongues. "Wow..."

While we watched them, we tried to figure out how they were cracking open the cones to get to the seeds. We could see them working the bracts apart, but had no idea how they were using their crossed bills to do it. Later that night, I got a few of my birds books down to see if I could find out. The answer was easy to find and was in the first book I opened. Bernd Heinrich, in his book Winter World, offered an explanation. He wrote that a crossbill's upper bill is two centimeters long and crosses over a one-half centimeter shorter lower bill. To open a cone bract, the bird inserts a partially open bill into a bract, then closes its bill. When closed, the bill tips separate the bract laterally by about 3 millimeters, just enough for the bird to open its bill slightly and use its barbed tongue to dip in and grab the seed (Heinrich, Winter World, page 37).

Eventually, Matty went off looking at tombstones and did a few rubbings to try to figure out dates and names on the oldest and most weathered stones,  and I did a quick sketchbook entry to record our day. We had been to Caesar Creek earlier for a picnic lunch and had seen lots of birds, but the White-winged Crossbills stole the show. In 2009, White-winged Crossbills showed up for a while in Cincinnati, and it was exciting too, but this year, the irruption seems bigger. I can't wait to see what else winter brings!

...sketchbook entry completed in the field. It was very warm that day...65 degrees F. 

To round out the post, I did a quick watercolor of one of the White-winged Crossbills we saw that day. I can't wait to get back out to see if more of these interesting birds are around. If you haven't done so already, you might want to pop over to the ABA Blog to read Nate Swick's post, "Help Monitor the Red Crossbill Invasion" (click here). You also might like Jim McCormac's post (click here) for a photo of a White-winged Crossbill's long tongue as it nabs a seed.

Happy birding, everyone!
