European Starling. - Campo Flicker
Sturnus vulgaris - Colaptes campestris
30-9-18 © Cora Rimoldi
On Saturday 30th of September we found a campo flicker building a nest in a tipu tree of the sidewalk. The campo flicker is not as common as the green-arred woodpecker so we are delighted to have it nesting at the reserve. For some reason or anohter only today did I come back to see the nest. I thought it would be feeding the little woodpeckers. Instead, there was a European starling feeding its chick..

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.

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
