Palm Warbler (Setophaga palmarum)
Wandering Glider (Pantala flavescens)
Tiger beetle, possibly a Hairy-necked Tiger Beetle (Cicindela sp., possibly Cicindela hirticollis). [I don't have access to a field guide at the moment! I'll correct this if I learn otherwise.]
Peregrine Falcon (Falco peregrinus) with avian prey (and trailing a dried eelgrass blade).
Gray Seal (Halichoerus grypus)
Very large unidentified ray actively feeding in shallow water near shore. This ray was at least 4-5 feet across! That's one tip of a pectoral fin raised above the surface. The white coloration below the water is the ventral surface exposed whenever the ray pivoted.
Horned Larks (Eremophila alpestris)
It was a beautiful day at the beach!
