Shiny Cowbird, Mejía, Arequipa

Some 10 years ago this bird came to Mejía. We even wrote an article in Cotinga about it's presence in Southern Peru, now it is everywhere.

So this parasite behavior from Sniny Cowbird is more and more common in this area. Hopefully it will not make any problems for some local bird species. I have seen Brown-Headed Cowbird in US, they did make a lot of problems for the Kirtlands Warbler, a rare bird in Michigan, parasiting their nest. The local nature guards had spesial traps to catch these birds and take them away from the area(killed or transported far away, I do not remember)

It is specially Rufous-collared Sparrows that are suffering in Mejía (luckily not a threatened species). We did the firs observations of Shiny Cowbird here 10 years ago. We are going to have them around the house all the time.
