Williams, L.E., Jr., and L.L. Martin. 1970. Nesting populations of 

 brown pelicans in Florida. Proceedings of the Twenty-Fourth Annual 

 Conference of the Southeastern Association of Game and Fish 

 Conmissioners, pp. 154-169. 



Aerial searches and mail questionnaires revealed 22 active nesting 

 colonies of brown pelicans ( Pelecanus occidental is ) on small islands 

 close to shore off the Florida peninsula and a number of additional 

 colonies in Florida Bay and the Florida Keys between 1968 and 1970. 

 The same nesting islands were occupied in most years. Nesting took 

 place during late winter and spring in Florida Bay and during late 

 spring and summer in colonies off the peninsula. The maximum 

 numbers of nests counted during 1968, 1969, and 1970 was 6,926, 

 6,100, and 7,690, respectively. This represents a conservative estimate 

 of 12,200 to 15,380 brown pelicans nesting during the period of the 

 census. Prebreeding age classes were not counted. 



Most colonies were in trees on small natural islands. One colony 

 on a spoil island in Anclote Sound was on the ground. At least 

 three other colonies were on wholly or partially filled islands. 

 Trees used for nesting had strong outer branches that allowed 

 unimpeded access to and from nests. Black mangrove ( Avicennia nitida ) 

 was the principal tree used on the east coast and red mangrove 

 ( Rhizophora mangle ) was the species most often used for nesting 

 on the Gulf coast, although black mangrove was important on the 

 Gulf coast also. The number of colonies and variety of nesting 

 cover used were greater in the Gulf. 



The adult population has apparently remained stable in Florida 

 during the past three years. The census techniques used in this 

 survey are not sensitive enough to reveal small changes in population 

 size; therefore, this survey gives no indication whether reproduction 

 has been sufficient to sustain this population size over a long period 

 of time. (A. A.)
