The missing link...bobolink!

CAPTAIN SAMS

Based on the overnight northerly winds and a radar image which "showed" lots of birds in the air along the east coast, I had a feeling that we would have a good day.  That prediction became evident after the first couple nets runs and by the end of the day we had banded 150 new birds and had 9 recaptures of 17 species.  Common Yellowthroats were by far the most common species with 97 of them banded.  We also had a couple of first-of-the-seasons such as Swainson's Thrush, Cape May Warbler, and Baltimore Oriole.  We missed Baltimore Oriole at Captain Sam's last year so it was good to get one this year.

The winds have shifted to the east which means tomorrow will be slower but we have a cold front coming through tomorrow night which will bring a whole new suite of birds to our area.  Unfortunately, the wind is predicted to be quite strong which will limit our ability to catch the birds in our mist nets.

LITTLE BEAR

If we thought yesterday was a good day, then today was mahhhvelous. Things seem to keep getting better since our two day lull. We nearly doubled our captures from yesterday with 69 birds and we even caught two first-of-the-season species for Little Bear (more like Big Bear). One being a Magnolia Warbler, which we expect more of throughout the season, and the other being a very special treat for everyone; a charismatic Bobolink. A bobo-what!? That's right folks, a Bobolink. These beautiful birds belong to the blackbird family and are close relatives to our friends the Red-winged Blackbird, Boat-tailed Grackles and even Baltimore Orioles. This ground foraging, seed eating bird was once called the Rice Bird due to its propensity to feed on cultivated grains. Unfortunately, this creature joins the ranks of other declining avian species across the Americas, which calls for action to help birds like the bobolink from further degradation!
