Boothe Park Hawk Watch 2015 Season

Boothe Park Hawk Watch 2015 Season

We are now well into the fall hawk watch season as sites across the country are staffed by citizen scientists engaged in counting raptors heading south for the winter. Various hawk, falcon, vulture, eagle, and kite species plus birds like the Osprey, Northern Harrier and even some owls can be tallied on conducive flight days at migratory hotspots often situated along ridges or at the edge of a body of water. Counting these birds helps keep track of raptor populations on an international scale, gauging the health of these important predator species that have often been threatened by human...

Heavy and low avian migration in Jamestown

Heavy and low avian migration in Jamestown

This past Wednesday, October 15, I was outside in downtown Jamestown, New York, for much of the night. An area of low pressure had moved by earlier in the day and precipitation had cleared. Clouds were thinning and moving east. There are plenty of unnatural noises to hear on a typical night in the City of Jamestown – music, people shouting, vehicles and often large trucks passing by. There was also an incessant yet subtle chorus of noises coming from the low levels of the sky in the form of avian flight calls! Birds were moving south and in strong numbers with almost endless peeps and...

Wind, climate change and raptor migration

Earth’s climate and weather play a direct and constant role in the lives of birds. At no point is this impact from mother nature more widely observable than during migration. Global winds shape the timing and track of bird movements across the continents and the sea. In this case I wanted to take a look at September 2014 and how it seems to have been a climatic “throwback” in the Northeast for our birds. If you talk to folks in many portions of New England the Mid-Atlantic about the weather in 2014 you often hear how it was very average in terms of temperature and...

Avian migration and high pressures – September 28, 2014

Did you enjoy the summer-like weather across the Northeast this weekend? At this time of year if it feels that gorgeous and benefits warm weather lovers it denies the birds a cooperative migratory flight. This radar grab from a few minutes ago shows very light migration across much of New England and the upper Mid-Atlantic thanks to a few weak areas of high pressure giving us this warmth and mostly calm or light southerly winds. One high is centered over Lake Michigan, another between Iowa and Missouri and a third in Virginia, with all three causing the only decent avian movement to be found...
