That's my bicycle in the background and luckily for me, I had my little Sony A6000 in my hands with the the Sigma art 19mm lens. I simply bent down to the birds level and used the tilt screen to frame my shot. I didn't even need a zoom as this little fellow was coming in rather close. I may return tomorrow with the Nikon d700 and the 70-200mm as I really don't want to get so close again and disturb the pair. What a neat experience it was though. Lets hope the weather doesn't bring any nasty surprises for these guys.
