Black-necked Stilt

A small flock of Black-necked Stilts flew out of the marsh on 20 February 2014 at the South Padre Island Birding and Nature Center. Stilts prefer wetlands with more vegetation than do avocets, though the two species are often found in man-made ponds. When breeding, stilts are less gregarious than avocets and often show more territorial behavior (Robinson et al. 1999). Silt numbers must fluctuate, since we saw far more stilts during our last visit to south Texas a few years ago. I suspect the availability of ponds must be a determining factor. This year was the fourth of relatively severe drought.
