My neighborhood has Northern Rough-winged swallows present every year from about this time until perhaps mid-June when they disappear (always hard to define when they're gone). They are common, foraging above and around the houses. Had my first of the season yesterday (March 4) as a quick flyby that I wasn't sure about, but confirmed one this morning. I know they've been around in more optimal habitats for some time, and some all winter, but. I'm curious about what is going on with their timing. Do they breed here early and then migrate (where?)? Possible that they go north or up elevation and breed again, or are they just done for the season and head south early. Anyone know?
