There's a robin in my garden

We've been cleaning a bit the garden, removing weeds and creating a more habitable space. Two green bags of removed plans later means a lot of new exposed soil, and for birds that calls for loads of food available! In minutes we had two robins around, not worried at all by our presence but excited by the number or caterpillars and other tasty stuff revealed. With a 300mm lens at hand it was the perfect opportunity for some bird shooting. Unfortunately fully zoomed the maximum aperture is f5.6, what means not enough speed with the existing light. Conditions were also quite windy, so I raised my ISO to 800 in an attempt of gaining enough shutter speed to hand hold my camera and get a decently sharp exposure. Robin
