  • Polytypic: 3 subspecies
  • Authors: Alex. E. Jahn, Philip C. Stouffer, and R. Terry Chesser

Demography and Populations

In Costa Rica, 5 of 18 (28%) nests fledged at least one nestling (Skutch 1966). In northeastern Bolivia, 17% of 158 nests monitored over three seasons failed, and of those, 33% failed during nest construction (n = 44), 43% during the egg stage, and 24% during the nestling stage (F. Hilarion and AEJ, unpublished data). Jahn et al. (2010d) were unable to genetically distinguish resident from migratory individuals of the nominate subspecies at a study site in Santa Cruz Department, Bolivia, suggesting weak population genetic structure across at least part of the range of the species.
