Pectoral Sandpiper (Calidris melanotos). Common to abundant migrant throughout state. Spring transients occur late February to early June, rarely early February and mid-June, peaking in April. Fall migrants occur mid-July to early October, rarely early July and November, peaking in mid- to late August (two early and one late December record may pertain to late migrant or wintering birds); juvenals arrive mid-August. No January or summering records. Marshes, mudflats, flooded fields, and other wet grassy areas.
Purple Sandpiper (Calidris maritima). Vagrant; only a few records (Cameron and Jefferson parishes) from winter and spring. Rocky shoreline or jetties.
