Deciding to get out and go for a walk, I went over to the nearby wetlands which was a refreshing change from all I have been going through lately. When I entered the marsh, a small party of goldfinches were busy feeding in amongst the thistles but flew off as I got closer. I did manage a quick study of them though. Insect calls were all around me in the long grasses, and bumble bees were busy collecting nectar and pollen from wild roses next to the path. A lone Song Sparrow sang a few times as I walker deeper into the marsh. Looking down towards an open channel of water, I saw an amusing sight - a musk rat was dragging a large branch full of leaves through the water and into its burrow on the opposite bank. It was forced to swim rather slowly though as there was a lot of resistance from all the leaves through the water.
As I stood watching, a male Mallard flew in, calling as it got closer. It splashed down near to where I was standing, quickly turned and emerged from the water onto a mudflat looking around. Close up, I could see that it was beginning to moult into its eclipse plumage – quite early in the year I would have thought. All the other male mallards I have seen around here are still in full breeding plumage. At this point, the bird still had all its flight feathers though but will soon have to choose a quiet corner of the marsh to stay while it loses then re-grows them. After undergoing a full moult, it will then somewhat resemble a female. When its flight feathers grow back in again, it will begin to moult once again, this time back into its breeding plumage. While I was studying the duck and taking some notes, I saw movement off to the side and a Killdeer came into view, amazingly close!
I spent quite a lot of time watching it and taking notes with a few quick sketches too. For the most part, it ignored me (since I wasn’t moving much) and continued to walk around the muddy area just in front of me occasionally dipping its tail (which allowed a brief flash of bright orange) and stooping to pick up small worms (probably bristle worms). At one point, it turned sideways towards me and dropped its left wing. I thought it was about to do its ‘broken-wing’ display which they (and a few other birds) do to lure predators away from their nests. But no, it then slightly turned its rump in my direction displaying the bright orange of its upper tail coverts (these are usually covered by drab tertial feathers and its primaries). After holding this pose for around 20 seconds or so, it lifted its wing back into its regular resting position then began feeding again.
Shorter-billed waders like Killdeer search for their food using sight, unlike many longer-billed waders that probe for their food. So a quick few steps forward then they stand still. If food is spotted, a quick dip to pick it up then on again for a more few steps. As it walked even closer, I saw how it would shift from foot to foot lightly pressing on the mud each time – this is supposed to help bring food to the surface. I also noted the area between its two outer toes were semi-palmated (partially webbed) but not between the two inner toes.
After a few more minutes of feeding, it stood on one leg and began to wing-stretch. Birds do this as a way of keeping their flight muscles loosened up as they often have to burst into sudden flight when a predator appears. They usually do one side first then after a while, do the other side. This involves lifting one leg and stretching it back while extending the wing and slightly spreading its tail. The whole process looks really beautiful, especially with this species because hidden under the somewhat drab plumage lies bright black, white and orange-patterned wings and tail! I felt especially fortunate to see it! Some species also lift both wings up above their backs, I expect also to keep their flight muscles limber. I have noticed that behavior in most smaller waders as well as larger ones such as Whimbrels, and even birds as large as Snow Geese! Eventually though, as enticing as this bird was, I moved on to see what else was about and left the Killdeer next to the resting mallard which now had its bill tucked into its scapular feathers.
