We usually see a spotted sandpiper.
About halfway along the boardwalk, I took this panoramic shot. Visible is the continuing boardwalk (almost a mile of it) through various habitats. The taller building to the right of the water tower in the centre is the 5 storey Birding and Nature Center.
The yucca palms are really starting to bloom in the Rio Grande Valley. This one is always an early bloomer beside the parking lot. Those spines are REALLY sharp.
