These Grey Wagtails have almost brought my work to a stand still at times. They nested 3 feet off the floor, in a busy work yard with 10 Forklift Trucks passing by every minute or so. The Female walked in front of the trucks, and every driver had to slow down, and let Mum pass. The male always approached from above on the yellow hand rails. In the last few days, the parents had to act like hummingbirds to feed the youngsters. Thankfully all 7 chicks have fledged now. With a little help from the workforce!
