At Least We Caught A Few Catbirds

Captain Sam's:

The past week has been slow, but I think today takes the cake. We only caught 18 birds in approximately 4 hours, half new birds and half recaptures. Our banding day was also cut short by some rain moving in from the ocean mid-morning. Looking at the 10-day forecast, we aren't due for another cold front until next Thursday - we can only hope it breaks up this banding rut and pushes some wintering birds onto the island!

Little Bear:

Couldn't agree more Sarah! At Little Bear, we only caught 13 birds (6 new and 7 recaps, of 5 of our most common species). Mercifully, some rain came in at around 10:30 to send us home early. But before we closed up, I took time to photograph a species we often take for granted here, the ever-abundant and vivacious Gray Catbird. Throughout our current slow spell, Catbirds have helped keep our numbers afloat, and their lively personalities infuse some energy into otherwise ho-hum mornings. Gray Catbirds are one of the most abundant and easy to observe bird species in the United States, breeding across much of the US in any shrubby area, including many people's backyards. They have an incredibly broad wintering range as well, from the mid-Atlantic coast, through the southeastern states and Central America, all the way down to northern South America. They are one of the most common captures at many US banding stations (especially in the east), and are undoubtedly the species that I've handled the most of in over 10 years of banding. Some days it is easy to feel tired of them, but they're certainly a quintessential part of the North American avian community.
