SHEARWATERSTHROUGH STORKS Followingthe highly successful pelagic trip off the Pacificcoast of CostaRica this past Ce.ntral America Jul, CostaRican birders (EA, AD, RD, RG, AO, JRZ)participated in a 24 Nov trip, this timeout of Quepos.With eachtrip, moreis learnedabout the distribution,seasonality, and abundance of seabirds off s. Central America.Among the Wedge-tailed Shearwa- ters observed 24 Nov was a Pink-footed Shearwaterabout 50 km ssw.of Quepos. Thisspecies, as far as known, is a rarevisitor to CostaRica in springand fall, with previ- ous records all much closer to the Cocos Is. On thesame trip, a juv. Red-hilled Tropicbird wasseen about 25 km ssw.of Quepos.Also, 3 dark-morphRed-footed Boobies were ob- served31.5 km ssw.of Quepos.This species is considered rare in Costa Rica so close to shore, and its seasonalmovements outside thebreeding season are poorly known.
