Although female and male parrotlets showed little difference in survival or site fidelity, this pattern is unlikely to hold for all tropical birds.
Thus, parrotlets could be an exception that proves the rule, if estimates of their survivorship are comparable to those of temperate zone species, but are low within the range of survival expected for tropical birds.
We modeled the effect of breeding status separately for male and female parrotlets because we found significant differences between the sexes in their local survival and resighting rates.
LD fell in love with a parrotlet - a little Blue Pacific who adored him in return.
We investigated nestling sex ratio variation in the green-rumped parrotlet , a small neotropical parrot breeding in central Venezuela.
