  • Light migration tonight (this morning)

    Just a head-up post with some of the weather data right now. Birds are on the move over New Jersey, although it’s a light flight due to the unfavorable winds at higher altitudes. The surface winds are absent, so birds appear to be taking advantage of the relatively still air. I’ll post the radar in […]

  • New data fields

    Okay- so in an effort to collect more relevant data alongside the radar, I’ve added a few new custom fields to the site. You should see them below. Direction and speed of surface winds and winds aloft (1,500 – 4,000 feet, or roughly 900mb) will each have an effect on nocturnal migration. Therefore I’ll focus […]

  • No (some!) migration last night

    Not much going on last night in terms of nocturnal migration, as the conditions were less than favorable. That said, there was alot of noise on the radar which made it hard to interpret. Fall is weird; there are lots of other things in the air that can give false positive results and last night […]

  • Trickle of migrants last night + forecast

    While not optimal, the calm winds did provide some opportunity for a few birds to move last night. Here’s the Fort DIX radar feed from sunset last night through sunrise this morning. The base reflectivity shows some activity just after sunset, increasing until about midnight, and decreasing quickly thereafter. Most of this is not bird […]

  • Very light migration tonight

    Winds are calm, but there are a few birds moving on the radar tonight. It’s hard to tell, and the signal is very noisy, but at least a small number of birds have taken to the sky. Migration conditions will be optimal once the cold front clears over the weekend, which is now shaping up […]
