Brown Thrasher (Toxostoma rufum) Science Article 1
abstract
The Brown Thrasher (Toxostoma rufum) in Florida exHibits a high rate of occurrence of an elongated sickle-bill type of abnormality. This observation became evident after having reviewed the literature on the subject and after I captured an apparently healthy thrasherwith an elongated, decurved bill in north Tampa, Florida
