 Hundreds of volunteers participate on the first weekend each May in the "Cape Parrot Big Birding Day" which is an annual count of the population throughout its distribution.The parrots are relatively easy to count at any forest patch due to their distinctive silhouettes, slow, 'rowing' flight and raucous calls.Counts are made in the evening as parrots arrive at roost patches and in the following morning as the parrots leave.
