Spotted sandpiper and chick
While vacationing near Hope, BC (Sunshine Valley), I noticed a sandpiper on a small gravel island in a nearby stream. I returned later with my camera hoping it would still be there. I was thrilled to find that it was, with a pair of chicks as well.
While photographing the adult, I noticed it repeated a peculiar up-and-down bobbing motion of its hind end. This is called teetering; you can see a video of it doing this here. This repeated tail-bobbing has resulted in some uncommon nicknames for the species including teeter-peep, teeter-bob, jerk-or-perk bird, teeter-snipe, and tail-tip.
What was even more interesting was that the chicks were engaged in exactly the same behaviour. I almost laughed out loud when I noticed this as I followed them with my viewfinder. Apparently, they do this nearly as soon as they hatch.
There is no understanding as to why these birds teeter, but according to one site I read, they may increase their bobbing rate when anxious or stop it altogether when courting. Whatever the reason, I admit to being enchanted by it.
Thanks for reading.
