Cranes in Flight

Today we headed south from Daroca to Laguna de Gallocanta-- a large lake where many thousands of common cranes stop on their  migration south to Africa. The lake is now mostly dry due to a continuing drought, but the cranes keep coming.  Here are two in flight, which I was fortunate to capture soon after we arrived. 

Even though we did see thousands, the cranes were mostly quite distant--even these were at least fifty meters away and quite small in the frame, but with ca. 20 megapixels in the file, I was able to crop severely. My current lens is Canon's new 100-400 II (a much improved version of the original 100-400), and with the 7D Mark II body (also new) it is the best combination for flight shots which I've ever used--by far.
