Black-necked Stilt Migration Map

Black-necked Stilts are always fun birds to see.  The black-white contrast is striking on top of the tall spindly red legs.  Based on the animated eBird maps below of Black-necked Stilt sightings, it confirms my experience that they are early migrants.  They arrive in Idaho in April and leave in September, whereas most migrants are arrive in May and leave in October.

The range of Black-necked Stilts is rather interesting.  Look at May's map marked to emphasize the highest concentrations: 

Below is's range map.  Looks like that stretch on the Mississippi River will have to be added.
