Black Necked Stilt
I came across this pair of stilts with two juveniles at Lake Parker in Lakeland, FL.
As I approached the male (I think) started his Keek-Keek-Keek call and tried to entice me away from the kids.
Here is one of the juveniles.
As I kept getting closer to photograph his chicks he started to swoop over my head
sometimes just a few feet away.
The black stilt is considered to be a threatened species.
