May 18, 2012Migration Report: 11 – 17 May 2012Diversity and abundance of migrants remained high across much of the US during this forecast period. (See last week’s forecast.) Presumably, this period and the next will be the last to have such diversity and abundance during this spring season,…

March 12, 2014Migration Highlight: Florida Peninsula and Keys, 11-12 March 2014In our first weekly forecast for spring 2014, BirdCast highlighted the potential for fallouts and concentration of migrants in the Florida peninsula:
“By midweek conditions favorable for migrant arrivals and departures are limited to Florida North to the Carolinas; and birders…
March 28, 2018Migration Highlight, 28-29 March 2018Team BirdCast highlights some relationships between migration and weather that could explain why our migration models predict migration in certain areas and not in others. Let’s take a quick look at the migration forecast for the night of 28-29 March 2018.
March 9, 2012Migration Forecast: 9 – 15 March 2012Expect a progression of good migration conditions very similar to last week’s. Conditions for bird migration will be favorable east of the Rockies and on the Great Plains over the weekend. By Monday and Tuesday these conditions make for good…
April 6, 2012Migration Forecast: 6 – 12 April 2012After an amazingly early start to spring migration across much of the eastern two-thirds of North America, we expect migration to return to a more typical schedule this week. Arrival dates should be only slightly ahead of average through the…
March 4, 2012Migration Forecast: 5 – 9 March 2012Watch for favorable migration conditions progressing eastward this week, affecting the Great Plains Monday and Tuesday and the Midwest and possibly East Coast on Wednesday and Thursday. A cold front approaching the West Coast will bring strong winds to the region…
May 4, 2012Migration Forecast: 4 – 10 May 2012As several low pressure centers and their associated precipitation progress across the country, migration levels will vary more than usual. Primarily light to moderate movements will occur across more southerly portions of the West, whereas precipitation and generally unfavorable winds…
March 30, 2012Migration Forecast: 30 March – 6 April 2012Conditions across much of the West look favorable for light migration to occur during the course of the forecast period, particularly toward the end of the week. The distinct exception is the Pacific Northwest, which is again forecast to receive…
April 27, 2012Migration Forecast: 27 Apr – 3 May 2012While most of Team eBird is down in Texas making Big Day history, I,David La Puma, have been charged with filling in for them in writing this week’s migration forecast. In doing so, I have also called upon a team…
May 25, 2012Migration Forecast: 25 – 31 May 2012Most of the last big pushes of spring migration will occur this week. Light to moderate movements will occur in many precipitation-free areas of the West. The Great Plains will experience moderate to heavy movements in many areas early in…
