Population Dynamics of the Wood Thrush in Southern Veracruz, Mexico'
The Wood Thrush Hylocichla mustelina (Muscicapidae: Turdinae) was studied on wintering grounds in the rainforest of southern Veracruz, Mexico, using mist netting, radiotelemetry, and field observation. Data were collected during three boreal winters (primarily November-March), and 46 individuals received transmitters. All sex and age classes were present, but difficulties in aging and sexing di...
متن کاملThe Relationships of the Wood Thrush (hylocichla Mustelina) : Some Indications from the Electrophoresis of Blood Proteins
The generic relationships of the Wood Thrush (Hylocichla mustelina) have been called into question by the works of Dilger (1956) and Bourns (1967). The four species of North American woodland thrushes presently referred (32nd Supplement to the A.O.U. Checklist 1973) to the genus Catharus i.e., Hermit Thrush ( Catharus @tutu) ; Gray-cheeked Thrush (C. minima); Swainson’ s Thrush (C. ustuluta); a...
متن کاملConnectivity of wood thrush breeding, wintering, and migration sites based on range-wide tracking.
Many migratory animals are experiencing rapid population declines, but migration data with the geographic scope and resolution to quantify the complex network of movements between breeding and nonbreeding regions are often lacking. Determining the most frequently used migration routes and nonbreeding regions for a species is critical for understanding population dynamics and making effective co...
متن کاملEvidence of large-scale source-sink dynamics and long-distance dispersal among Wood Thrush populations.
Source-sink dynamics are commonly thought to occur among Wood Thrush (Hylocichla mustelina) and other songbird populations, allowing for the persistence of populations with negative growth rates ("sinks") through immigration from populations with positive growth rates ("sources"). Knowledge of source-sink dynamics is important for management and conservation because the removal of source habita...
متن کاملSkin thrush in early infancy.
Thrush is generally regarded as one of the rarer infections of the skin of the newborn and young infant, but its occurrence is probably more frequent than its recognition. The high susceptibility of the oral mucosa to Monilia albicans during the early weeks of life is well known and it would be surprising were it limited to this structure. Invasion of the alimentary tract and other internal org...
