1922.] TRINIDAD BIRDS. 175 



UricK (Bull. Dept. Agr. Trinidad IX.. 161) records them as 

 eating the caterpillars of Remigia repanda during an outbreak of this 

 pest on Sugar Cane at Couva in July 1 909. 



According to T. I. Potter a bird of this species killed a small 

 sugar bird {Coereba luteola) which he had just liberated from a cage. 



In spite of the name Tick Bird, by which the species is so 

 generally known, it appears to eat ticks rarely. In Porto Rico 

 A. Wetmore examined the contents of 41 stomachs and found only 

 one tick {Bull. 15 Porto Insular Experiment Station p. 60). The 

 habit that the bird has of following cattle on the pastures appears 

 to be more with the intention of eating grasshoppers disturbed by 

 the animals in their wanderings, than with any idea of removing 

 their ticks. 



76. Crotophaga major Gmel. Greater or Marsh Tick Bird. 



Leotaud No. 195. 

 This bird is much rarer than the preceding and differs from it 

 in its slightly larger size, more glossy colouring, less shrill cry, and by 

 the keel on the upper mandible ending about half way down instead 

 of being continued to the point of the beak. 



I have only seen this bird on one occasion on July 4, 1918, at 

 La Fortunee and know nothing of its habits. 



77. Piaya cayana Lmn. Bucutu or Coucou-manioc. 

 Leotaud No. 188. 

 I shot a specimen of this bird at Palo Seco on March 7, 1920, 

 which was, in company with several others, following an army of 

 hunting ants and catching the various insects which tried to escape. 



The stomach was much distended with food and contained six 

 large grasshoppers, six cockroaches of two different kinds, one 

 cricket, one winged ant, two small beetles and one centipede. 

 78. Diplopteryx naevius, Linn. Trinity. 

 Leotaud No. 187. 

 A group of five birds of this species was seen at St. Augustine 

 on November 5, 1920. I have no record of food or nesting habits. 



Family RHAMPHASTIDAE Toucans. 



79. Rhamphastes vitellinus, Licht. Yellow-and- White- 

 Breasted Toucan. 

 Leotaud No. 177. 



The bird is not rare in the forest districts. 



I saw one pair at Palo Seco on July 5, 1919, and again on 

 March 7, 1920. 



I examined the stomach of a specimen shot on Tucuche on 

 April 1, 1918 and it contained half a seed and a few small pieces of 

 the skin of some red fruit.
