BirdCast will soon return for Fall 2017! Favorable migration conditions for light to moderate flights become more widespread across the West, while the East sees a mix of marginal and locally favorable migration conditions with local light and moderate movements punctuate an otherwise summery pattern. Please check back in the coming week for the first official forecast and analysis posts!

With this season’s migration underway, the BirdCast team would like to highlight the potential for an unusual migration event associated with predicted weather in the Gulf of Mexico region. The first significant cold front likely to interact over the Gulf of Mexico with incoming trans-Gulf migrants is predicted to pass through the region from 17-20 March. Let’s take a moment to review the current conditions while considering some of the (simplified) mechanics of this fascinating system.

For those out birding from the mid-Atlantic through New England and west to the Appalachians and the eastern Great Lakes, today was a wild day of birding. Several blogs have captured the ornithological events spawned by Sandy’s arrival onshore, and…

The center of the circulation is mostly ashore near Atlantic City, NJ as of 8PM EDT, the system is now behaving more like a Nor’easter though still with some tropical characteristics, and the effects of Sandy are widespread and dangerous….

The remnants of Sandy, huge as they are, have a circulation that has just passed Philadelphia, PA. All of the meteorological forecasters involved in predicting the path of this system did quite an amazing job – now, team eBird and…

System uses BirdCast data to enable real-time lighting adjustments during peak migration events and reduce the number of birds colliding with buildings

The remnants of Philippe, a long lived hurricane, tropical storm and depression, and post tropical cyclone, are coming ashore in northern New England and the Canadian Maritimes.

Spring migration is in full swing, and knowing when peak migration will occur in your area is valuable information! Here we provide a sortable table of peak periods of spring bird migration for the largest cities by human population size in the contiguous US.

In our last post, we highlighted an area of southerly flow that is forecast for Sunday – Tuesday, 17-19 February 2013, from portions of Texas to the western Appalachians. Below, we provide a short animated clips to show the forecast…

Two interesting patterns may spice up the mid-February birding scene next week. High pressure building into the Southeastern US should bring a period of warmer, southerly flow to many areas of the Gulf Coast by Monday. These conditions may facilitate…

April’s Super Pink Moon will be visible after sunset and reach peak illumination at 11:33 P.M. EDT on 26 April 2021. For those wishing to see birds migrating at night, if the sky is clear, point a telescope or strong pair of binoculars toward the moon, particularly if you are in a location where the BirdCast model predicts medium to high intensity migration.

Southerly and southwesterly winds and rain will keep most birds grounded through Wednesday. However, a wind shift to the Northwest and clearing skies on Wednesday evening should open floodgates for migration – expect moderate to heavy movements across the area….
