Migration Weather Update (9/29)

[Bryan Guarente]

COBirders,

Not much to report from this cold frontal passage.  It is a shallow blast from close-by and the convergence pattern is not good for birds to stop over in CO.  Yes, we will see new birds today compared to yesterday that will undoubtedly be migrants.  No, there is not a single birding location in CO that looks like it is going to be the greatest benefactor of the winds.

Keep your eyes peeled as there will be different birds today and you might be lucky enough to find the one or two in your area that are rarities.
