Conservation Genetics Resources, 2015
We isolated novel microsatellites from the crested caracara (Caracara cheriway) with a shotgun pyrosequencing approach. We tested 80 loci for polymorphism among 20 individuals from the threatened Florida population. Fourteen loci were polymorphic. The mean number of alleles was 2.21 (range 2–3) and the mean observed heterozygosity was 0.41 (range 0.15 ...

Use of Anthropogenic Nest Substrates by Crested Caracaras
Southeastern Naturalist, 2015Abstract Caracara cheriway (Crested Caracara) typically nest in Sabal palmetto (Cabbage Palms) in Florida and isolated thorny shrubs (e.g., Celtis pallida [Granjeno]) in Texas. The species has not previously been reported to use anthropogenic nest substrates.

Factors influencing detection of nesting crested caracaras
The Journal of Wildlife Management, 2011AbstractManagement of crested caracaras (Caracara cheriway), focuses on nests identified during surveys. If no nests are found, management can be suspended. Thus, false negatives can have substantial consequences. We surveyed 49 breeding territories to assess factors with the potential to cause false negatives in detecting nests of crested caracaras ...

A habitat model to aid the conservation of crested caracaras
The Journal of Wildlife Management, 2017ABSTRACTNorthern crested caracaras (Caracara cheriway) in south‐central Florida are threatened by habitat loss, which is ongoing at local and regional scales. A tool capable of predicting effects of habitat loss on caracaras, and whose predictions can inform conservation strategies at multiple scales is imperative.

Effects of Double Brooding on Productivity of Crested Caracaras
The Auk, 1998-During at least one of three nesting seasons, 13 breeding pairs of Crested Caracaras (Caracara plancus) in south-central Florida made a second nesting attempt following a successful first attempt. Ten pairs successfully fledged young in both attempts. Only early nesting pairs attempted a second brood.

Southeastern Naturalist, 2007
Abstract Analysis of regurgitated pellets of Caracara cheriway (Northern Crested Caracara) at a site in south-central Florida produced a wide variety of insects and spiders from 34 families and at least 72 genera. Species identified occur in dung, on carrion, and in both aquatic and terrestrial habitats.

Breeding Biology and Productivity of Florida's Crested Caracaras
The Condor, 1999I studied the breeding biology of Crested Caracaras (Caracara plancus) in south-central Florida from 1994 through 1996. Reproductive activity was monitored year-round on 30, 48, and 55 territories, respectively. Pairs remained on breeding territories throughout the year and exhibited strong fidelity to the nest site between years; however, annual ...

Conservation Value of Private Lands for Crested Caracaras in Florida
Conservation Biology, 2001Abstract: In southcentral Florida, where agricultural lands are being converted rapidly to urban development, much of the remaining nonurban habitat occurs on privately owned cattle ranches. We studied the Crested Caracara ( Caracara cheriway ), a threatened bird of prey ...
