Re: [cobirds] Migration Weather: Thursday Sept 2 through Friday Sept 3

Steve,

I didn't particularly think today was going to be good. Tomorrow is a better chance by a bunch. Birdcast, for clarity, is about whether there will be birds seen on radar. It is not necessarily about where the birds will land so be careful with that assessment. Birdcast certainly has its place in the conservation world and can inform the birding world (if those are different). My forecasts are a different role than what Birdcast offers and both, I believe, are beneficial just to different audiences. 

Good luck tomorrow.

For what it is worth…. I checked Birdcast this morning pre-dawn, and was getting excited for banding possibilities at Clear Spring Ranch (El Paso Co). It was a dud. Maybe my slowest September day ever at CSR.

Few Chipping Sparrows (none netted), fewer warblers. Netted 8 birds all morning - banded 3, saw 2 more warblers. I DID band a young Red-eyed Vireo, and a Hatch-year Dusky Flycatcher, but it was SLOW.  The big events for the day were - (1) 500+ Common Grackles flushed from a field in one giant flock by a Prairie Falcon, and (2) 22 Western Kingbirds lining the fence on the way out - my second biggest arrival of those ever.

Hoping for more this weekend -

COBirders,

This morning, the cloud cover is relatively low, and I am sitting out on the patio right at sun-up to see if there are any birds calling while they are passing by.  No luck so far, but the winds aren't great for migration yet.  The day is young though.  Right now, the pattern looks like this:

Best of luck out there.  May the birds concentrate in your area one day.
