Large-billed Tern
Phaetusa simplex
30-9-18 © Cora Rimoldi
As we had already assumed the reserve would be closed on Sunday 30th due to the Saturday's storm. The program was to walk along the sidewalk and find the large-billed tern, which Horacio had spotted on one of the islets at the Brasil end on Wednesday. And there it was with its robust yellow bill tucked up at the back. We were lucky since it awoke right away and action began. It timidly bothered the pochards, which did not react. Before such indifference the tern picked on the silver teal on the left. The teal did move aside due to its cocky attitude. Satisfied the tern began to preen. And the first raindrops began to fall but...

we wanted to see the tricoulored back with open wings and stayed. Again the tern charged at the pochards, which did not get upset. Defeated it took flight, made a big turn to finally sit on the pole. Satisfied with the show we returned to Viamonte. The last part of the video is repeated in slow motion.

As we were walking back to Viamonte and much to our surprise the tern surpassed us and gave us another flight demonstration. It flew in long and pronounced waves sliding down to the water and gaining height. It was clearly fishing. It did pick the water on one occasion but we did not see the tern catch anything.

We normally watch the tiger-heron catch a fish or an eel, here the prey is yellow-billed teal duckling. The duckling belonged to a family in Canal Viamonte and this tiger-heron may be the one nesting a bit further on a tipu tree. The Saturday before the ducklings had been attacked by a Harris's Hawk and saved their skin. Their parents protected them but this Saturday this duckling was not that lucky. The video does not show the tragic end.

Nacunda Nighthawk
Chordeiles nacunda
19-9-18 © Julián Hernández
(View in full scene recommended. Click on bottom right icon)
"A nacunda nighthawk (Chordeiles - Podager- nacunda) taking off from a vegetation mat in Coypu Pond. It flew off when two caracaras (Caracara plancus) landed on the same mat searching for food. The Southern lapwings (Vanellus chilensis) moving around began to scream, chase the raptors causing a hell of a mess among all the species. Ducks also took off and so did birds (of different species) as quick as possible and in any direction. The nacunda flew in big and high circles, then round the pond flying low, near the water. The Reserve was closed on that day, though walking along the sidewalk (always carefully) gave us this pleasant surprise. Time: 5:30 pm, sunny day with scattered clouds and hot". Julián Hernández

Sirirí híbrido/Hybrid Whistling-duck
15-9-18 © Sergio Cusano
When comparing the hybrid with the fulvous whistling-duck below, th hybrid has practically the plumage of the fulvous whistling-duck in its body, except for the black and white barring on the flank. It is on the head where the wite-faced whistling-duck's characteristics are evident

Three of the most common swallows of the reserve
Golondrinas/Swallows and Martin
Blue-and-white Swallow Pygochelidon cyanoleuca
All-year round swallow. Ventraly white with black undertail coverts. Dorsally blue. Small size just like the white-rumped swallow.

Golondrinas/Swallows and Martin
White-rumped Swallow Tachycineta leucorrhoa
All white ventrally. Dorsally blue and white rump. This characteristic differentiates it from the chilean swallow Tachycineta leucopyga, which comes from the south to spend winter
8-9-18 © J. Simón Tagtachian
Golondrinas/Swallows and Martin
Grey-breasted Martin Progne chalybea
Bigger in size than the previous ones. It comes to spend summer. Ventrally white with greyish. Dorsally bluish black

These are the three commonest swallows. The Brown-chested Martin Progne tapera has not popped up yet. Unlike the others which combine white and blue, though different hues, the brown-chested Martin combines it with brown

Harris's Hawk and Southern Caracara
Parabuteo unicinctus - Caracara plancus
Gavilán mixto/Harris's Hawk
28-8-18 © MON
Quite a fight between a caracara and several hawks near the Middle Path in direction to Viamonte. A Harris's Hawk flied low with something in its feet, a ball of vegetal fibers similar to a nest. A Southern Caracara was chasing him. The chase lasted one or two minutes. They crossed the Lizard Path and the caracara tried to get hold of the nest. Suddenly two other hawks appeared and other raptors which I could not see well. There were 4 or 5 raptors which were very excited. The hawks attacked the caracara, which kept trying to get the nest. All this scene on the wing.

The caracara stopped for an instant, and so did the hawk, but the rest lasted little. Again the chase began and the hawk flew towards the Gull Pond. We lost sight of them.

Microspingus melanoleucus
Monterita cabeza negra/Black-capped Warbling-Finch
30-8-18 © J. Simón Tagtachian
Not too frequently do we have the chance to see the black-capped warbling-finch's tail completely open. Moving restlessly and quickly in the bushes we can hardly discover this detail. But we must pay attention to it.
The tail feahters are known as rectrices. They are used to steer and brake when in flight. Only the central pair is attached to the pygostyle (last ossification of the column formed by several vertebrae fused). The remaining feathers are inserted in a fiber adipose mass.  
Monterita cabeza negra/Black-capped Warbling-Finch
© J. Simón Tagtachian
The number of rectrices changes with the species and it is paired. Feathers are counted from the center outward. Passeriformes have 12 rectrices.
Monterita cabeza negra/Balck-capped Warbling-Finch
© J. Simón Tagtachian
When closed and from a dorsal point of view the central pair of rectrices is seen. The remaining feathers are stacked beneath them. As the tail spreads, the rectrices slide in a fan-like way. Half to one side and the other half to the other side. This is when we can see this white triangular design on both sides in the Black-capped Warbling-Finch.
Monterita cabeza negra/Black-capped Warbling-Finch

Ventrally the tail looks white when closed since the outer rectrices which are almost white all along form the other face of the tail.

When opening the tail the black rectrices are exposed
