We had already said that the environment of the Duck Pond was ideal for wintering plovers. However since it is so far search must be patient and exhaustive. It is small and its brown colour blends it in the environment. Its little runs help detect it.
It is not the only one we are waiting for. the dotterel also vistied the reserve in winter. Both share this picture of 2006, which coincidentally is 31st of May.

Other winter birds to look for
On the list of Winter birds appear all the birds related to the winter time which have been photographed. Germán Pugnali prepared another list, where most of them are old records with no documented support. Besides, he adds some which were not spotted in the reserve, but in the surroundings, which become potential birds.

Recent taxonomic changes
As phylogenetic studies improve the taxonomic board is being reordered. In October 2016 the SACC passed the proposal 723 which introduced significant changes in the location of orders. Taking into account only the families represented in the reserve the most striking move is the Order Columbiformes being placed rather ahead on the list following the Podicipediformes due to the close relation with this order. At the same time the orders Cuculiformes, Caprimulgiformes and Apodiformes follow Columbiformes due to the close relation with this order. Present order: Anseriformes, Galliformes, Phoenicopteriformes, Podicipediformes, Columbiformes, Cuculiformes, Caprimulgiformes, Apodiformes, Gruiformes, Charadriiformes, Sphenisciformes, Ciconiiformes, Suliformes, Pelecaniformes, Cathartiformes, Accipitriformes, Strigiformes, Coraciiformes, Piciformes, Falconiformes, Psittaciformes, Passeriformes. Orden anterior: Anseriformes, Galliformes, Podicipediformes, Phoenicopteriformes, Sphenisciformes, Ciconiiformes, Suliformes, Pelecaniformes, Cathartiformes, Accipitriformes, Gruiformes, Charadriiformes, Columbiformes, Cuculiformes, Strigiformes, Caprimulgiformes, Apodiformes, Coraciiformes, Piciformes, Falconiformes, Psittaciformes, Passeriformes.

The family Thraupidae also had a reordering of species, changes in scientific names, besides the inclusion of the saltators, which had been removed from the family Cardinalidae and placed in Insertae sedis till the correct family was assigned. On this site saltators stayed in the family Cardinalidae). All these changes can be appreciated in the Cast. They are not the last only the most recent.

Preening and exposing the speculum

It has been missing in the Coypu Pond since more than a month. The last record is in the Gull Pond and was detected by chance when enlarging a photo.

Floating vetegation is ideal for jacanas. They move about pecking incessantly. But here everybody is on the wing

This parrot was abandoned by a woman in the Middle Path. The Center was informed about the animal. This woman had cared for the parrot till its feather grew but could no longer have it with her.

There were five Poopiza species: P. ornata Cinnamon Warbling-Finch, P. nigrorufa Blakc-and-rufous Warbling-Finch, P. cabanisi Grey-breasted Warbling-Finch, P. torquata Ringed Warbling-Finch and P. melanoleuca Black-capped Warbling-Finch. Phylogenetic studies have determined that this group is polyphyletic, that is they have not evolved from the same common ancestor. So they have been separated. The first two have remained in the genus Poospiza and the last three have been changed to genus Microspingus: Microspingus cabanisi, Microspingus torquatus and Microspingus melanoleucus..
