Welcome to my photo site! Thanks for comments and sorry if I don't reply...
nomenclature: birds orders and families are classified following the International Ornithologists' Union 2014, used also in Wikipedia.
when an identification is uncertain I use "sp.", or when I think that a genus or species are right but I'm not sure I use "cfr." (it means "compare with"), especially to facilitate the search, however must be verified, when possible, before use of picture.
