Last night there was more of the same weather we have had for the last week; strong east winds dominated the night. There was a shift in wind around 3am to ESE but that only latest one hour or so. There was activity on the radar exiting Cuba last night, second night that we see migrants trickling out of Cuba. Some birds made the brave flight from the East but in very small numbers. By far the best migration of night was from the east coast to the west coast. Birds could be seen exiting the Miami and Melbourne radars headed over to the west coast, some rain fell in the morning as the birds were in flight in the St. Pete/Sarasota area. There could be concentrations around the area today, any one birding out there? For the last three days conditions have been best out west, any birds landing?
Well down here we should have a small increase in migrant activity, might not be noticeable to the eye but birds have been exiting our area for the last week and we still have been seeing some new stuff (ie..Red-eyed Vireo).
That means there has been an influx of birds in direct correlation with birds exiting the area. We might not notice that new birds have arrived because we don’t see anything “new”, but in fact new birds may have come in. If the birds leaving and the birds coming are all the same species give or take a few different ones, we may not notice the change in population. With that said go out and bird the possibilities are endless out there, who knows what rarity we will find next.

All observations will be greatly appreciated, please com back and visit Badbirdz2. Good Birding.

  1. I’m fascinated by your connection of weather with migration. It’s obvious of course, but I never gave it much thought. Spring migration is so exciting. I don’t want to miss any of it!
