Bird Survey organized by the COARECS - Saturday, March 25th
A very nice day to count birds. See the results.

The top bird without any doubt was the osprey. Though this eagle had been seen a few times a long time ago this is the first photographic record of it.
The Coypu Pond was completely covered with floating vegetation from side to side. Wood Storks, spoonbills and the Chilean Wigeon which delighted us with their presence left the pond. Wood Storks were spotted but on the wing

The Chilow Wigeon has few sightings concentrated in winter. More abundant in the south it migrates to the north at that time. It appeared in groups and stayed a very short time in the reserve.
This solitary individual arrived on the 20th of January approximately and after a month and a half it is still here. It shares the islets with other anatids, in this case it is with White-faced Whistling-ducks and Yellow-billed Teals. Good opportunity to compare sizes. The voices heard in the video are White-faced Whistling-Ducks'.
