El 30 de setiembre encontramos un carpintero campestre construyendo un nido en una tipa de la vereda. El carpintero campestre no es común como el carpintero real, por lo tanto que estuviese anidando era una alegría. Por h o por b o por mal tiempo recién hoy volví. Pensaba encontrarlo alimentando a los pichones. En cambio, había un estornino alimentando a la cría.

European Starling - Rufous Hornero
Sturnus vulgaris - Furnarius rufus

Marcelo's video shows the most negative aspect of the European Starling in the reserve. The eviction of a native species - a Rufous Hornero from his nest

27-10-18 © Marcelo Gavensky
I was shocked because the fight was long, even much longer. A starling went out and threw the chick to the floor. Only one hornero stayed. I think the starling killed the other one which remained dead inside. Very, very shocking.
Pichón de hornero/Hornero chick
27-10-18 © Marcelo Gavensky
It was the new nest in the front, outside the reserve. The horneros brought food to the chick. The starling goes in and the horneros get desperate. One of them gets into the nest and fights the starling. “ M. Gavensky

A stork with a neck swollen by something fighting to escape. It turned out a big eel which, once expelled and reswallowed, insisted on staying kick and alive in the pond. Finally the stork gave itself up and took flight with an empty crop.
