Last night nocturnal migration was definitely apparent on the radar. A weak front pushed through the lower southeastern states last night; it can be seen on the SE radar. Upper level winds were favorable for the first big nocturnal migration event of this season thus far. Birds took advantage of the clear skies behind the front allowing them to make good ground last night. Birds departing are clearly seen following the front over AL, TN and Ga. Migrants flowed off the coast of Pensacola and Alabama with a SE trajectory. We expect new faces from the panhandle to St. Pete area today. Further down the state there was some migration but not as good as in the North due to the winds not being optimal. Some activity was picked up by the Miami radar but given the density we don’t expect much to have landed. For the third night activity was picked up leaving the Lake Ingraham area headed towards the Keys, anyone out there looking for shorebirds? The flats along the bayside should have a new influx of birds as a result of this movement. The central flyway looked amazing last night behind the front; you can sneak a peek at it on the SE radar. Good Birding to all, come back and share your sightings as this site works best when it is a collaborative effort.

    Yellow Warbler-1 female
    American Redstart-10

  2. hot,sticky late morning walk through the Mangrove Bay Neighborhood produced a good assortment of warblers. I’d advise anyone with some time to get out to one of the local hotspots. There were over 20 warblers in the flock, all feeding in the treetops. I thought I had a Canada, but I had only a fleeting glimpse and was unable to relocate it.
