occasionally flying or circling high in the air. On April 15 one came over 
the boat as I was crossing to Culebrita and I shot but failed to secure it. 
7. Butorides virescens cubanus Oberholser. CuBAN GREEN HERON. 
— Green Herons were fairly common in the mangroves bordering the bay 
known as Ensenada Honda. ‘They were very wild. <A few were seen on 
the lagoon called Flamenco and two were collected on April 9 and 13. 
8. Florida cerulea cerulescens (Latham). Lirrte BLuur Heron.— 
This species was heard and seen occasionally about Ensenada Honda. One 
was collected February 9, 1899, by Dr. J. D. Milligan of the “ Fish Hawk.’’ 
9. Phonicopterus ruber Linneus. FLaminco.— Flamingoes were 
said to have been found formerly on Culebra Island. The lagoon known 
as Flamenco receives its name from this bird. 
10. Marila affinis (Eyton). Lesser Scaup DucKx.— At the time of 
my arrival on Culebra Island there were about twenty-five ducks on the 
lagoon at Flamenco. None were secured but they were supposed to be 
this species. Eight were still present April 21. 
11. Peocilonetta bahamensis (Linneus). Banama Prntart.— A 
few of these ducks were seen with the lesser scaup ducks on the lagoon at 
Flamenco. April 9 two birds in worn plumage were secured by Don Pedro 
Marqués at Playa Brava. April 15 I found about twenty-five in a nearly 
dry lagoon on Culebrita Island and secured several. The flight of these 
birds is swift like that of a teal but on the wing the long neck makes them 
resemble Dafila acuta. This flock contained birds of both sexes about to 
breed and among them was one immature bird two-thirds grown. 
12. Falco sparverius loquacula Riley. Porro Rican Sparrow 
Hawk.— A common resident. These birds were nesting at the time of my 
visit and were very tame. A female taken April 6 had an egg in the ovi- 
duct nearly ready to be deposited. Others examined had the tips of the 
rectrices worn to spines through abrasion in the nesting cavity. These 
sparrow hawks were alert and noisy. One was seen pursuing a Red-tailed 
Hawk screaming shrilly. And one day as I was climbing a steep hillside 
one came darting swiftly down at my head and was dropped only a few 
feet away. They were feeding largely on lizards picked expertly from rocks 
or tree trunks and were seen pursuing birds unsuccessfully. 
13. Buteo borealis (Gmelin). Rep-Tarbep Hawk.— Red-tailed 
Hawks were seen occasionally soaring over the forested hill tops. 
14. Pandion haliaétus carolinensis (Gmelin). Osprey.— Single 
Ospreys were observed circling over hills near the sea on April 8 and 17. 
This species is probably a regular winter visitant. 
15. Fulica caribea Ridgway. CaripBpEAn Coot.'— April 13 before 
daylight one of these birds was shot at the border of a lagoon. The skin 
of this bird was stolen by a cat. Another coot was seen on April 19 but was 
not secured. These birds I thought were migrants. They may nest in 
one or two localities. 
11Tt has been found recently that the coot from Porto Rico is F. caribea instead of 
F. americana (cf. Wetmore, 1916, p. 34).
