The winds over Pittsburgh had been favorable final night time and the birds had been anxious to go north. There was excessive migration over southwestern PA and BirdCast tells the story on their new Migration Dashboard.
Since 2017 we’ve been checking BirdCast for stay migration maps and forecasts. This 12 months they’ve supplemented the maps with a Migration Dashboard that gives a wealth of county-by-county data together with anticipated species every night time.
Let’s check out this morning’s dashboard for Allegheny County, PA.
As of 5:00am at this time, greater than one million and a half birds had flown over Pittsburgh however they had been slowing down. Dwell site visitors was sparser (50,700 birds in flight), they had been transferring extra slowly (12 mph), and so they had been shedding altitude (1,400 ft). That is regular; they are going to land earlier than daybreak.
The rely of birds peaked at midnight (graph on left). It was a extremely good night time for April (graph at proper.)
You may see an extra cause why the numbers dropped at 5:00am by evaluating these two Dwell Migration maps. At 1:40am the map in Pittsburgh is vivid yellow with migrants however a darkish gap (no exercise) develops in Ohio and West Virginia at 5:00am. Birds stopped flying there as a result of it was raining forward of a chilly entrance.
