You’ve recently watched a small flock of songbirds fly over while watching an autumn morning’s migration unfold, perhaps hearing a sharp “tick, tick… tick, tick” even before seeing the birds. Congratulations, you’ve seen a Purple Finch, this week’s species on the move.

Olive-sided Flycatcher is another interesting species on the move that we would like to highlight. With western populations breeding significantly farther south than those in more eastern boreal forests of Canada and the northern tier of the US, the potential to examine patterns of migration progression and differences in migration progression between populations is excellent.

Strong northeasterly winds in the western North Atlantic may hearken the arrival of small (very small) numbers of Northern Wheatears in eastern North America. Several have been reported in the last days, will more arrive soon?

At this point you have heard the stories for the west about bird mortality, but perhaps you have not heard the stories about species on the move out of the mountains. BirdCast will feature evolving stories about eruptions from higher elevations, and this week we highlight Mountain Chickadee.

Spring migration is now in full effect in many areas, with the beginnings of some peak windows of passage approaching for the southern latitudes of the US in the coming two weeks! Light to medium intensity movements will occur in the eastern and southern US.

Although most of the US is firmly in the midst of typical summer conditions, fall migration is already under way for many species. BirdCast will begin its weekly series of forecast and analysis and species on the move in early August,…

BirdCast returns with some species on the move discussions for spring 2020! Killdeer is a familiar and hardy shorebird with a generally high tolerance for human habitation and landscapes, and the earliest migrants of this species have been on the move in recent weeks.

An interesting pattern of Gray-cheeked Thrush arrivals in the central US during April led the BirdCast team to investigate a potential explanation. We looked to the wind.

Franklin’s Gulls may be on the move far to the east of their normal autumn range in the coming 24-72 hours, as an intense storm system continues to move across the country toward the Atlantic Ocean and entrains and displaces individuals and flocks of this long-distance migrant. Observers in northeastern North America should be on the lookout, especially along coastlines, lakeshores, and rivers, from Wednesday through Friday.

We are nearing the window of peak migration through the US, and many species are on the move!

In the past decades birders have become increasingly aware of rapid changes in the phenology of bird movements in parts of the United States, noting what species are early, when birds are late. The power of eBird for highlighting these…

In June 2017 numerous observers around the Northeastern US commented that Dickcissels were more obvious, and in greater numbers, than years in recent memory. Team BirdCast take a quick look at this pattern and how it changed (or not!) over the weeks that followed.
