Medium to high intensity migration spanned the latitudinal breadth of the central US last night.

Peak migration periods in many areas of the contiguous US are approaching, and we can visualize the approaching waves of migrants in space and time.

A line of intense storms approaching the western Gulf Coast will make for interesting and challenging conditions for inbound trans-Gulf migrants. The strength and the timing of frontal passage, as well as its projected extent over water, suggest potential for…

Team BirdCast has not spent much time highlighting the center of the continent this spring, so we would like to take a moment to rectify this!

In the early morning hours of 30 April, a strong frontal boundary is moving toward the Atlantic. This front has strong storms with intense precipitation, and in advance of its passage favorable winds for bird migration.

As of approximately 3pm Central Daylight Time, some intense thunderstorms are about to interact with an inbound trans-Gulf migration event.

An exciting migration event unfolded yesterday morning and this morning in Southern California, as many thousands of birds continued their nocturnal movements well into the first hours of day light.

As of 20 April 2020 the BirdCast live migration maps switched color palettes to match migration forecast maps. The new color palette is more suitable for viewers with green-, red-, or blue-color blindness, and is perceptually uniform in color and black-and-white (see this interesting talk by the designers of this so-called “viridis” color scale).

This update focuses on the migration activity in the West where several nights of significant movements were apparent recently.

A brief migration update – another frontal boundary has started to move into the Gulf of Mexico region , and there are a number of interesting events to share this evening with its passage.

A frontal boundary is approaching the Gulf of Mexico region, likely moving over water late on Thursday evening. Fallouts and concentrations of migrating birds are likely along the Gulf of Mexico coast for several days.
