Traffic Report, Northeastern US: 13-20 October 2016

The week of 13-20 October 2016 has so far featured some large movements on 13, 14, and 19 October. This movements have been primarily to the south-southwest and southwest.

Traffic Report: Northeastern US, 23-29 October

Migration events over the last week varied substantially in size. Last Friday night (23 October) saw a particularly large movement (see below to watch), followed by no (or extremely small) movements on the following night. Successive nights saw decreasing migration traffic rates; remember, a major low pressure system moved through the region with lots of precipitation.


Traffic Report: Northeastern US, 8-14 October 2015

See our first report or scientific paper (currently a preprint) for more information about […]


Traffic Report: Northeastern US, 1-7 October 2015

Migration events over the last week were respectable in size, but we did not see the widespread, monster movements that often grace this time of season. For example, in our paper characterizing nocturnal movements in the northeastern US, the largest movements we reported occurred during the first week of October. Remember, migration traffic rate is defined as the number of birds from 0-3,000 meters above radar stations moving hourly over a 1 km line drawn on the ground.


Traffic Report: Northeastern US, 23-29 September 2015

Once again, Team BirdCast is excited to bring you reports of migration traffic rates in the northeast United States, calculated from a completely automated pipeline of algorithms. The images you see in Traffic Reports present the migration traffic rate (MTR), direction of bird movement, and speed of bird movement. See our first report or scientific paper (currently a […]


Traffic Report: Northeastern US, 3-23 September 2015

Team BirdCast is excited to debut daily reports of migration traffic rates in the northeast United States. Each night, from local sunset to local sunrise in the Eastern time zone, a BirdCast server downloads radar data from 16 stations in the northeastern US. These data are composed of every scan of the atmosphere made by these radars during this time […]
