BIRDS OF CUBA 49 



65. Falco peregrinus anatum Bonaparte. 

 Duck Hawk; Halcon.' 



Recorded by Gundlach as an annual winter visitor from the United 

 States. He writes that it tarries about the shores of lalces and swamps, 

 ready to dash forth after Ducks, Coot or Gallinules. He also makes special 

 mention of its change of speed in flight. 



I never have seen a single Duck Hawk in Cuba, and I conclude that 

 now it must be very rare. 



66. Falco columbarius columbarius Linne. 

 Pigeon Hawk; Halconcito.i 



The Pigeon Hawk is rare in Cuba and Gundlach doubted whether 

 this typically migrant bird ever remained to breed, although Gosse had 

 observed the nest in Jamaica — doubtless a very exceptional case. What 

 then was my surprise on April 27, 191 5, when my friend Cervera brought 

 me a pair shot while nest-building in the Botanical Gardens just outside 

 the city of Havana. These birds are now in the Museum of Comparative 

 Zoology (nos. 67,408 and 67,409). They differ in no wise from other 

 Pigeon Hawks. 



67. Falco sparverioides Vigors. 

 Cuban Sparrow Hawk; Cernicalo. 



The Cernicalo is very common every^where. The light and rufous 

 phases of plumage have caused much confusion. They, however, signify 

 but little. I have a large series before me and it may be of interest to list 

 the birds. 



' These two names are used only by bird students; the guajiros call most Hawks Gavilan.
