Three raptors
Tres rapaces/Three raptors31 8 16 © J. Simón Tagtachian
This composite photo by Simón gave me the opportunity to talk about these three raptors which along with the Chimango Caracara are ever present at the reserve. They belong to two different families - Accipitridae, Roadside Hawk
Rupornis magnirostris (left) and Harris's Hawk
Parabuteo unicinctus (right), and Falconidae, Southern Caracara
Caracara plancus (center) and Chimango Caracara
Milvago chimango absent in the photo. The Harris's Hawk and the Southern Caracara are practically the same size (47 and 48 cm respectively), whereas the Roadside Hawk is rather smaller (34 cm).

The Family Accipitridae includes hawks and eagles. The family Falconidae, caracaras, falcons, forest-falcons and kestrels. They share characteristics like the fleshy cere which covers the base of the bill, the hallux (hindtoe) which opposes the three forward toes, the habit to capture prey with feet, reversed sexual size dimorphism (female is bigger than male), binocular vision. Among the differences, the colour of the eyes. Falconids mostly have brown eyes and accipitrids, hazel, red, yellow or white (like the Roadside Hawk).
All accipitrids build nests out of sticks. Falconids instead nest in tree cavities or reuse abandoned nests adding sticks. There are some exceptions like the Southern and the Chimango Caracaras.
Most accipitrids have a well marked supraorbital ridge which makes them look fierce. Falconids have 15 ossified toracic vertebrae.
Molt of flight-feathers in accipitrids is from primary P1, the innermost to P10, the outermost. Falconids molt primary P4 and proceed outward and inward.

These two families shared the Order Falconiformes along with the family Cathartidae (vultures). In 2008 the results of genetic studies separated them into three orders. Falconiformes (Family Falconidae), Accipitriformes (Family Accipitridae) and later the Family Cathartidae also had its own order Cathartiformes. These results kept the affinity between Accipitridae and Cathartidae but provided not very conclusive evidence about the relationship between Falconiformes and Psittaciformes and Passeriformes. Once this evidence was corroborated, in 2011 Falconiformes along with Psittaciformes were moved to the end of the Non Passeriformes arranged in this way: Falconiformes, Psittaciformes and then Passeriformes.

Photos by Eduardo Ibarra
Eduardo Ibarra tells uscuenta "I met people working for MA of CABA and told me about the progress of the works. I told them about some sectors with rubbish and took them to see the masked ducks at Viamonte. They said they would see to it. God knows whether they will do something but I brought up the issues I can see everyday". Photos taken on 18th and 19th of August

Saturday 27th, a rainy day and Sunday 28th, the reserve was closed Anyway I walked the outer sidewalk: It was very cloudy and cold. Bad news There was not a single masked duck. As for the other waterbirds, the coscoroba swan is still nesting and I could not see the little herons because they were covered by the adult. Too many pied-billed grebes - I counted 10. Three spot-flanked gallinules. Two at the Brasil end, the other one at Viamonte end.

Grey-breasted Martins have already arrived and they gathered at the antenna as usual. But the caracara came and drove them away. The antenna was used as a stop by a pair of caracara during the absence of martins. Some sticks can be seen.
