There are a few things you can do to try and find a parrot nest. First, you can look for areas where there are lots of parrots congregating. This is often a good indicator that there is a nest nearby. Secondly, you can look for telltale signs of a nest such as sticks or leaves piled up in a particular area. Finally, if you have access to binoculars or a telescope, you can try scanning trees and other potential nesting sites for any sign of movement which could indicate the presence of a parrot nest.
