After the fair is over.

I visited Hastings Park today for the first time in over a month, due to a combination of travel on my part and the annual PNE on the park's part.  Workers were busy de-constructing the booths, stages and displays.  To my mild surprise, a Green Heron was at the usual perch across from the fishing dock.  Green Herons appear to be more tolerant of human presence than I had originally thought.  A couple of Wilson's Warblers and a couple of immature or female Common Yellowthroats were present.  A group of ten or so Bushtits contained a couple of short-tailed individuals that may have been fledglings only a short time ago.  Few other birds of note were seen.

The ponds continued to be nearly covered with a film of duckweed.  Only a area of perhaps 20 metres in diametre surrounding the aerator at the north end of the pond remained open.

A few blossoms of fireweed and an even fewer blossoms of Wapato or Duck Potato remained.  One of two of what I first thought were bees were visiting the small number of persisting Snowberry flowers, most of them having matured into the white berries from which the members of the Symphoricarpos genus get their common name.  Further research leads me to believe that what I was seeing were Bald-faced Hornets.

Other ripening fruits were seen on Red Hawthorn, Mountain Ash, Blue Elderberry and Pacific Crab-apple trees.

Leaves on a variety of trees were changing colours and even falling.  The season was changing, with no doubt.  Bring on September.

Mallards and Herons

One morning a few days ago a Great Blue Heron was perched on the railing of the bridge at the east side of the main pond, eyeing something below.  As I approached, the heron flew off.  When I crossed the bridge, a hen Mallards and her brood of very young ducklings swam underneath.  In the previous week two new Mallard families, both with nine ducklings, had appeared.  Great Blue Herons are known to prey on ducklings but, after careful counting, all nine floating fluff balls were still there.

The next morning, while looking for a singing Red-winged Blackbird at the south end of the pond, I heard a squawk coming from behind some reeds.  Out flew a Great Blue Heron vigorously pursued by a female Mallard.  I know that nature is red in tooth and claw, but I must admit I was was rooting for the under-duck.

Mallard plumage

I have been thinking about plumage in Mallards, for several reasons.

I have been watching the older family (hatched in early May) of Mallard ducklings grow up and have been looking for any signs of the appearance of sexual differences in plumage, so far unsuccessfully.  Research turned up the concept of a "drake feather" but this develops only after three or four months of age. That age appears to be when differences in bill colour and breast feathers occurs, as well.  I could not categorize any of the ducklings as to their sex.

I have also been watching the adult male Mallards moving into eclipse plumage.  Their bright glossy green heads are fading to a dull purple.

Soon the only clue left that will differentiate a male Mallard in eclipse from a female will be the greenish cast of its bill.
