Robert O’Toole | 2016 Roseate spoonbill hatchlings on the nest Sigma 150-600 S @ 600mm (900mm equivalent) Nikon D500 1/800 f/6.3 ISO 1600 manual mode Auto-ISO -1.7

Spoonbill chicks are irresistibly cute, but since the adults prefer to nest farther back than other birds, you need a very long lens to isolate the nest to be able to capture the chick’s interaction close up. Here I used a crop sensor body with the 150-600 to give me the equivalent of a hand-holdable 900mm, which was the perfect solution.
