Ten more days of fall migration- more or less

This afternoon as I stepped out my front door, I heard the pleasantly mellow note of an Eastern Bluebird- a species that I have never detected in or from my urban yard before, and which only occurs in my part of the city in passage.  

Shortly thereafter, a White-throated Sparrow chimed a series of its distinctive peek notes from behind my neighbor's house- another one that normally graces my 'hood only when passing through.

It's probably not coincidence that these birds showed up on a day of north winds following a frontal passage- such conditions provide a nice tailwind for migration.  It may be late November, but their migrations are still in swing for the next ten days or so.  Various fall migrants continue to arrive through November- but the pace drops off precipitously in the first week of December.  After that, among land birds, only a few atypical species continue to arrive.

So enjoy these last few days of southbound arrivals- and wait for the first northbound Purple Martins, just around the corner at the end of January!
