White-faced Whistling-Duck
27-12-16 © J. Simón Tagtachian

The posture of these two white-faced whistling-ducks is a common image in this species. They are preening one another, that is they are allopreening. Preening is a common behaviour in all the species, but allopreening is only observed in those species with strong social ties like the white-faced whistling-duck. With no apparent reason one bird approaches another, directs its bill to the neck and begins preening. The other one reacts doing the same thing. Either adult-adult or adult-juvenile indulge in this activity. Beyond the benefits of preening- keep free from parasites and with tidy feathers- allopreening reinforces the bonds in the group

Light morph. María José saw the Swainson's hawk take flight from the the Gull Pond. It flew towards the northeast as it gained altitude to jump on the thermal current.

We saw this hawk at about 8 am and once again when we were leaving. The half-opened wing call our eye. It screamed just like it did in the morning. When we saw the photos we realized the bird was ringed and that the wing was hurt. We went for help. Two girls from the Center appeared and we took them to see the hawk. Apparently this bird was rehabilitated in the center and later released. It must have had an accident of some kind..

Bird Survey organized by COARECS - 17th December 2017
Just about to begin summer antoher bird survey took place. A hot day and very sunny too. At noon 104 species had been counted. Number which was easily increased judging by the photos of birds that had not been seen. See the result Observadores/Birdwatchers

While the adult was with the chick a black-crowned night-heron appeared. I feared for the chick knowing the predatory habit of the heron. Everything is ok. Moreover when the adult walks away and the chick stays practically face to face with the heron. The chick went aroun the heron and managed to reach safety
