Autonomous sound monitoring shows higher use of Amazon old growth than secondary forest by parrots
Forest regeneration may reduce the current loss of species due to tropical deforestation, but little is known about the extent and inter-specific variability of this effect. We compared the probability with which nine parrot species use old-growth and secondary forests in a ~400km2 Amazonian landsca...

We compared the probability with which nine parrot species use old-growth and secondary forests in a ~400km2 Amazonian landscape, while considering two types of habitat use: perching and flyover use.

Forest regeneration may reduce the current loss of species due to tropical deforestation, but little is known about the extent and inter-specific variability of this effect.
