IBLers... I know it's Christmas Eve, but this GCBO project looks interesting, and besides, three shrikes and you're out! / bad pun, long story...

happiest of holidays, all y'all = )

Biologists from the Gulf Coast Bird Observatory and the Texas Midcoast NWR Complex are banding Loggerhead Shrikes for a new study aimed at determining habitat partitioning differences between migrant and resident shrikes during winter along the Texas coast. Banded shrikes will have two color bands on the left leg and a color band and a metal band on the right leg. Some are receiving transmitters and the antenna can be seen hanging out behind the bird if the bird has a transmitter. Note that it is often not possible to see all the color bands as shrikes like to sit down over their legs. The antenna is usually easy to see though. This project will last for four winters (this being the first). This winter we have banded four shrikes in the area around Brazoria NWR (one on the tour loop, one on CR 208, and two in the neighborhood along Bastrop Bayou across from Demi John) and five shrikes in the Sargent area (one on Sargent Ranch Road, two on Heron Street, one in the neighborhood along CR 201 and one near the GIWW. We have received a lot of reports through the Bird Banding Lab for the shrike along the tour loop at Brazoria NWR so I figured I’d pass the word along to everyone to look for the others. If you see one, you can report it to the BBL or to me directly. We would very much appreciate a lat/long for your sighting as we can use this data to determine territory size. We will be rotating banding sites each winter so I will post an update with the banding sites for next year. Thanks much for your help!
