Not a good night for passerine migration, as thunderstorms pounded our area keeping all birds down. As has been reflected on the Jerseybirds list, this does not equate to bad birding conditions. Shorebird numbers are high at most locations (Sandy Hook, Brig, Stone Harbor), as well as Black Terns (various locations), Roseate Terns (Sandy Hook), […]

Interestingly, the surface winds dominated last night’s non-migration. While winds at 800mb were out of the northwest, those at the surface were strong and out of the east/southeast. Last night’s radar showed no migration over New Jersey, nor over the northeast as a whole. Monday night looks like the next possible migration event, with winds […]

A few birds were moving last night before the line of thunderstorms came through and shut them down. Since the front moved from west to east, places like Garret Mountain are probably good this morning. Good Birding

Woohoo! It’s so nice to see them keep coming like this! Last night was similar to the night before, with a moderate movement of birds over the Garden State, and heavy movements across the eastern and central flyways. Winds, again, differed depending on the altitude, which makes for some difficult radar interpretation, but there was […]

The radar last night leaves much to be desired…and way too much to interpretation. So here are the conditions: Surface winds had a southwesterly component, while winds aloft were primarily from the west. I’m thinking that this explains why you see a mix of S–>N and N–>S flows in the velocity image. Of course, with […]
