Lots of field flickers but no field around

With civilization encroaching and natural areas availability shrinking, animals either go down extinction alley  or adapt. I am glad to register that a family of field flickers has just moved in to an area in urban Foz do Iguaçu already shared by a growing number of bird species. I have taken pictures of them right on the spot where busy avenues Republica Argentina and Jules Rimet meet. The Field Flicker (Colaptes campestris) is called "pica-pau-pau-do-campo" in Portuguese,  "carpintero campestre" in Spanish, "pic champêtre" in French and Ypekû ñu in Guarani - the native language to Jungle Lands that best translate Nature and its phenomena as far as tropical forests goes from the Amazon all the way down to Uruguay, Argentina and the whole of Brazil.
