I think that it is a bird and a frog, the bird I don't know ( I have presum=
ed luscinia megarhincos but it can be other bird, the frog I think is Hyla =
meridionalis, but it can also be, hyla arborea or rana perezi. the place is=
well studied by scientists because it is a place that is part of the Unive=
rsity of Lisbon,and in the papers there are only these tree frogs and the s=
