Being resubmitted as it did not appear in 30 minutes. Gus makes an excellent point that you can sometimes get valuable information on landing radar that you would not have predicted when making a report the night before (see Stephane Perrault's report from Hempstead Lake yesterday).  But I

I have been reviewing these radar maps for the last few years, almost on a daily basis during migration seasons. I think there are few points to be considered during reading these maps: (especially for NYC birders) (check the archived radar loops on this site as I explain my point:

The radar reflectivity that we see is proportionally to the amount of water in a given volume of atmosphere as sensed by the radar. Birds are largely made up of water and hence they are highly reflective. Hence, when we see high radar returns from birds it is due to the density of birds in that

I think I might have run into some musings at the Forest Park water hole today, maybe even some hallucinations. But once again, numbers surely weren’t as high as the radar reflectivity might have suggested. I would say there were more birds than there had been, but nothing to write home about

The radar pattern tonight is similar to what it was last night.  High reflectivity and high velocity in a NW direction.  Does this mean tomorrow will be birdy or quiet? I can’t say for sure but I’d like to share some thoughts about it.   Steve brings up the issue of promising radar reports
