Hi Federica,
Assuming that the output of the OCR text extraction always contains the name of a place in uppercase followed by the name of an animal in lowercase, the function isstrprop can then be used to determine the indexes of the uppercase and lowercase letters. This can then be used to create the variables places and animals as shown below:
data = 'MOUNTAIN bird';
idxplace = isstrprop(data,'upper');
idxanimal = isstrprop(data,'lower');
places = data(idxplace);
animals = data(idxanimal);
