Zusammenfassung

"The mobility and rapid dispersal of young yellowcrowned parakeets from the area of their nest contrasts with the behaviour of red-crowned parakeets
(Greene 1990). Greene found that many red-crowned
parakeet fledglings went onto the ground or into low
vegetation after fledging, and remained near their
nests for about 2 weeks."

"Greene (1990)
found that red-crowned parakeets laid their first 3-
4 eggs at daily intervals and the remainder at 2 or
3 day intervals; and PJD has observed the same pattern with captive yellow-crowned parakeets."
"Greene (1990) found that red-crowned
parakeets started incubating after they had laid their
fourth egg."
