As the days buy the farm along to shorten as well as summertime begins to lose its intensity, attentive birders abide by flocking demeanour inward many species. For almost birds (goldfinches are an exception), their breeding flavour has ended as well as their territorial instincts accept faded; migrants get together inward flocks to cook for their southward journeying acre many permanent residents flat flocks to evade predators as well as to ameliorate the efficiency of their foraging.
Last evening, I encountered a flock of 30+ barn swallows, strafing a nearby lake to fuel upward for their journeying to South America; then, this morning, I watched every bit a flock of eighteen snowy egrets moved southward higher upward the South Platte Valley. Among other belatedly summertime migrants that locomote inward sizable flocks are blue-winged teal, Swainson's as well as broad-winged hawks, shorebirds, mutual nighthawks, American white pelicans as well as Franklin's gulls. Non-migrant flocks of cedar waxwings, doves, robins, starlings as well as diverse blackbirds are too increasingly mutual every bit summertime winds down.
While the influx of wintertime songbirds volition non laid out until mid October, these belatedly summertime flocks offering around excitement every bit birders endeavor to recover from the mid summertime doldrums. Better yet, they are a preview of tumble migration glasses as well as hint at the cool, crisp days that prevarication ahead.
