During the August long weekend I visited the Eagleson storm water ponds a couple of times to check out the shorebird habitat – the southern pond is starting to dry up, leaving a huge swath of the smelly, muddy pond bottom exposed. The usual Spotted Sandpipers and Killdeer were present, but at least four Lesser Yellowlegs, one Greater Yellowlegs, and five Least Sandpipers had joined them. It’s still early in shorebird migration, so I expect the diversity will increase as the season progresses.
The number of herons hunting at the ponds has also increased lately, which is typical this time of year as the birds disperse from their breeding grounds to look for good feeding areas. At least two Great Blue Herons, two Great Egrets, and three Black-crowned Night Herons are around; I haven’t seen any Green Herons yet so far, but expect they will show up shortly. Because there are so many herons here, and because they perch and feed out in the open, they make excellent targets of study; I shouldn’t be surprised that they are starting to draw the attention of local photographers. I ran into one this weekend specifically to photograph the egrets and herons; doubtless there are others.
It’s been a fantastic week both in terms of weather and finding wildlife. Last Saturday I visited Andrew Haydon Park to check out the developing mudflats in the western bay. Unfortunately the water was rising again, so the expanse of sand has diminished. Several swallows were flying out over the river (species unknown), and I realized a small bird flying with them was not a swallow but something else – a good look revealed a small shorebird being chased by one of the swallows! The shorebird headed toward Ottawa Beach before circling back and landing on the small muddy area in the western bay, where I was able to identify it as Semipalmated Sandpiper – my first of the year!
One of the best parts of mid- to late summer is seeing all the young birds that have left the nest foraging and learning how to survive in the wild. Some secretive species become a little more visible after post-breeding dispersal, and this includes one of my favourite types of birds, the herons. Once they arrive in the spring, they can be difficult to find outside of a few well-known rookeries once breeding season gets under way, as they prefer secluded bodies of water well away from human activity. However, once the young fledge and leave their nesting grounds, herons begin to appear in shallow ponds and creeks in local parks, both adults and young alike.
On August 7th I decided to return to Mud Lake, a place I hadn’t visited in a few weeks. First, however, I stopped in at the storm water ponds to check if anything new had arrived. I saw two Northern Flickers flying over, a species I occasionally observe here, though not on every visit. Only two herons were present, a Great Blue Heron and a Black-crowned Night Heron. Three Barn Swallows were swooping over the water, and I found a young Common Yellowthroat lurking in the vegetation close to the water. Best of all, there were some new shorebirds present – two Solitary Sandpipers and a single Least Sandpiper!
After discovering the Saffron-winged Meadowhawks and Eastern Amberwings on Sunday July 30th, I returned again Friday after work, as well as on Saturday and Sunday. I checked the small crescent bay each time for the meadowhawks, to no avail; in fact, I didn’t see any meadowhawks on any of my visits at all. I got lucky and found one of the male Eastern Amberwings on the same mat of vegetation on Friday after work, but didn’t see any females. The male amberwing was much further out this time, and as it was an overcast afternoon, the resulting pictures weren’t as nice as the ones from my previous encounter.
I have never really spent much time looking for odes at the Eagleson storm water ponds, as most of my outings start there first thing in the morning when it isn’t hot enough for many dragonflies to be flying. However, after seeing the unidentified female spreadwing there on Saturday morning, I decided to head over on Sunday after my visit to the Old Quarry Trail. While I’ve seen Common Green Darners, Twelve-spotted Skimmers, Autumn Meadowhawks, Eastern Forktails, Tule Bluets, and Familiar Bluets there since the reconstruction, the arrival of the unidentified spreadwing and even the Delaware Skipper made me wonder whether other species had taken up residence recently. I wasn’t expecting anything too exciting or unusual, but I figured I might at least see some of the common pond skimmers found nearby at places like Bruce Pit and Stony Swamp. Perhaps I should have raised my expectations a bit, for what I found there surprised me!
I didn’t intend to spend three hours at the Eagleson Storm Water Ponds on Saturday morning. However, it was one of those days where the longer I stayed, the more I saw, and the more I saw, the longer I wanted to stay! The birds were quite active, with two woodpecker species (Downy Woodpecker and Northern Flicker), eight Canada Geese (one group of seven and a singleton by itself), a family of Yellow Warblers, a Turkey Vulture flying over, 16 Barn Swallows perching on the roof of one of the buildings on the west side, two Belted Kingfishers, and several young Common Grackles following their parents around, begging for food. All four heron species were present, including one Great Blue Heron, one Green Heron, one Great Egret, and one juvenile Black-crowned Night-heron and two adults.
