Stochastic and catastrophic events may strongly impact the dynamics of wild populations. Annual fluctuations in rainfall may affect parrot populations, but few studies address the impact of other stochastic or catastrophic events on their population

The Maroon-fronted Parrot (Rhynchopsitta terrisi) is a threatened species endemic to pine-oak (Pinus spp.-Quercus spp.) forests in “sky islands” of the Sierra Madre Oriental in Mexico. We measured parrot (n = 10) home ranges during the breeding s

Ornithologists have hypothesized that some tropical forest birds avoid snake predation by nesting in isolated trees that do not have vines and canopy contact with neighbouring trees. Here we review two complementary studies that support this hypothes

We studied Thick-billed Parrot (Rhynchopsitta pachyrhyncha) nest-site density and social nesting behavior from 1998 to 2001 in Madera, Chihuahua, Mexico. The species formed high-density nesting clusters; 45 nesting attempts (30%) involved nesting pai

Thick-billed Parrot (Rhynchopsitta pachyrhyncha) nest sites were studied during a six-year period (1995–2000) at six nesting areas in the Sierra Madre Occidental in Mexico. Nests were found in 187 snags or live trees of seven species, which average

We studied productivity and nesting success of the Thick-billed Parrot (Rhynchopsitta pachyrhyncha) during a 7-year period (1995–2001) in five nesting areas at the Sierra Madre Occidental in Mexico. Two breeding areas continue to be the breeding st

Although the poaching of nestlings for the pet trade is thought to contribute to the decline of many species of parrots, its effects have been poorly demonstrated. We calculated rates of mortality due to nest poaching in 23 studies of Neotropical par

The Military Macaw (Ara militaris) and the Great Green Macaw (A. ambiguus) are species whose close relationship is reflected in their morphological similarity as well as their geographic ranges. Military Macaws have a disjunct distribution, found in
