    Abstract

    Estimating genetic divergence among populations is crucial for the conservation of many threatened and endangered species (Allendorf & Luikart 2007). Many management programs are concerned with resolving phylogenetic and taxonomic uncertainties among taxa in order to prioritize conservation efforts below the species level (e.g. subspecies, evolutionary significant units), which is important because much existing taxonomy may not reflect the underlying genetic diversity (Moritz 1994, Crandall et al . 2000). Unfortunately, basic information on population genetic divergence is lacking for many threatened species, hindering conservation and management actions such as translocations and reintroductions (Moritz 1999). The Snail Kite Rostrhamus sociabilis is a medium-sized hawk that feeds mainly on freshwater snails and is considered a wetland-dependent species (Beissinger 1988). Three Snail Kite subspecies are currently recognized based on morphometrics (Sykes et al . 1995): (1) Rostrhamus sociabilis plumbeus , distributed in peninsular Florida and Cuba; (2) Rostrhamus sociabilis major , distributed in Mexico, Guatemala and Belize; and (3) Rostrhamus sociabilis sociabilis , distributed in Nicaragua, Costa Rica, Panama and South America (Fig. 1). The separation of subspecies based on size variation alone has been questioned (Sykes et al . 1995).
