We saw many pairs of adults and a large number of well-grown juveniles, and, at a point 4 miles south of Washington Beach, we collected a brood of three small juveniles that had only recently hatched. The breeding season apparently was drawing to a close, for several adults in our collection were in postnuptial molt and showed marked gonadal regression. From July 6 to 9, a few small groups of birds were noted, but large groups were not seen until July 10, when several flocks of up to 60 individuals were found along the coast 3 to 7 miles south of Washington Beach. Specimens (12): [M], 38904, testis 4.5 × 2 mm., 58 gm., 3 P old, brood patches refeathering; [M], 38905, testis 5 × 2 mm., 59 gm., 4 P old, brood patches refeathering; [M] juv., 38903, 6.2 gm.; 2 sex?, 38901, 38902, 5.7 and 6.2 gm., 4 miles south of Washington Beach, July 6. Male, 38907, testis 5 × 2 mm., 56 gm., 7 P old, brood patches refeathering; [F], 38906, ova to 1 mm., 61 gm., 3 P old, brood patches refeathering; [F] juv., 38908, ovary inactive, 54 gm., in body molt; Camp 1, July 6. Male, 38910, testis 6 × 3 mm., 60 gm., 4 P old; [F], 38909, ova to 1 mm., 57 gm., 4 P old, brood patches refeathering; Camp 1, July 8. Male, 38911, testis 2 × 1 mm., 55 gm.; juv., 38912, no weight or sex recorded; Camp 2, July 9. =_Numenius americanus parvus_= Bishop: Long-billed Curlew.--Lone individuals and groups of two to five were noted occasionally along the beach each day. In total, some 30 to 50 birds were counted, but some individuals may have been recorded more than once on different days. Specimens (2): [M], 38918, testis 4 mm., some fat, 459 gm., Camp 2, July 9; [F], 38933, ova to 1 mm., no weight recorded, Camp 2, July 8. Our assumption that some or all individuals seen by us were nonbreeding, summering birds is supported by the fact that our specimens are referable to the small, northwestern subspecies, _N. a. parvus_, rather than to _N. a. americanus_; the latter breeds south in the eastern United States to south-central Texas (A.O.U. Check-list, 1957:181). Loetscher (1955:27) saw a flock of 39 curlews near Tamós on June 30, and he notes that nonbreeding birds are fairly common at all seasons in Veracruz. Similarly, the species is present throughout the year on the central Gulf coast of Texas (Hagar and Packard, 1952:8). Authors of the Mexican Check-list (1950:94) do not mention the possibility that birds of this species recorded in México in July are summering rather than migrating. Twelve supposed migrants seen along Laguna Chila (Cacalilao), Veracruz, by Coffey (1960:291) on May 31, 1957, may have been summering birds.
