I snuck closer to inspect, but was hissed at vehemently by the sitting goose's partner, who was not deterred by my approach, but rather, made it abundantly clear that I was not welcome so near. I soon figured out why: The sitting goose's large wing was shielding a small gaggle of goslings!!!
After a while, a fuzzy, yellow head poked up from under the wing, and Mother Goose turned her neck around to preen her baby, then poked it back into position next to its siblings under her broad, feathered wing.
I was lucky to get close enough for a kind-of-okay shot of the babies snuggling in together, before her partner made it clear that that was enough excitement for one night!
As I remarked to my own partner, who had accompanied me on the evening's geocaching adventures, it was odd that this family would choose a noisy train yard to settle down in for the night.
"Maybe", she replied, "they like the industrial look, like we do!"
