 Habitat Level 



Sources of information at the habitat level were cited in the tables. 

 Trophic relationships, except where noted, were not specific to Chenier 

 Plain. These relationships vary somewhat both geographically and with time; 

 thus the static view presented in the tables may be somewhat misleading. 

 The information may be used without much error, however, as generally indic- 

 ative of the kinds of foods a particular species consumes. Constraints of 

 anatomy, physiology and behavior of a species usually limit the kinds of 

 food it can consume to a relatively narrow range. 



Seasonal peaks of abundance given for birds refer to the state as a 

 whole, and not to specific habitats. Species whose peaks occur in spring 

 and summer are generally those that spend the winter months in Mexico, 

 Central America, and South America, returning in the spring to nest in the 

 coastal zone. Those that peak in fall and winter usually nest to the north 

 of the coastal zone. A third category of birds, the transients, breed for 

 the most part to the north of the coastal zone and winter to the south. 

 Year-round residents utilize coastal habitats both as wintering and as nest- 

 ing grounds.
