Estero's Tropical Kingbirds

This year the Kingbirds at Estero Lando Grande are mostly Tropical. The Couches and the Tropicals are almost identical. Some birders claim they can tell them apart by their beaks but their song is the identifying feature. Later this month the Couches will be more prevalent.  Tropicals are typically seen over water where they pick of insects. I caught one looking at a bug!
