The Spotted Sandpiper is usually solitary, so when two forage together, it can prove interesting.
Two sandpipers spent their initial time together stalking and eating sandflies off the beach.
Each fly was grabbed and swallowed in well under a second.
“Now that we have had a good dinner, would you care to dance?”
When was the last time anyone watched tigers mating in the wilds of British Columbia?
OK, truth in advertising. The tigers in question are beetles: Western Tiger Beetles.
These beach dwellers use their great speed to chase smaller insects and grab them with large, sickle-shaped, mandibles. On this occasion, the beetles did seem a bit distracted.

The Spotted Sandpiper is widespread along the shores of lakes, ponds, and rivers. It also has the unusual characteristic of a sexual role reversal. The female is larger, sexually aggressive, and polyandrous — that is, it mates with multiple males, each of which is then left to incubate and brood (what it thinks are) its own chicks.
A year ago, I posted a picture, sandpiper piping, of a spotty that was calling and strutting. I didn’t know what was going on; now, I do. It was a female making an aggressive sexual display towards a nearby male. This last week, I watched this interaction repeatedly.
Having arrived at a dock, a female repeatedly harassed two males. They pretty much ignored her. Here, the female performs her courtship display on tiptoes with wings and tail outstretched.
Such a display is directed towards a particular male and accompanied by a weet-weet call.
“No, no, please don’t leave — weet-weet.”
Finally, the two males flew off. This is the female chasing after them.
It was an unexpected experience. I was crouched low (and I thought, inconspicuously) on a forest hillside taking pictures of wildflowers when a family hiked by, paused, saw what I was doing, and asked, “Are you Alistair?” So it was that among my blog’s largely unknown subscribers, I had a rare accidental meeting with one of them.
It was also an uncommon meeting with the orchids I was photographing. The fairy slipper (Calypso bulbosa) is the first orchid to emerge in the spring and, of the eight local wild orchids I have photographed, it is loveliest.
I am used to seeing the fairy slipper in groups of two or three, so this crowd was special.
However, the grandest view is that of a single profile.
This spring has been a strange. Insects, usually plentiful, have been sparse — but not absent.
In a field of dandelions, both hover flies and solitary bees (but, not social bees) flew from flower to flower seeking nectar. It was fairly easy to take pictures of them on the dandelions, but I sought shots of them flying between the flowers.
A mining bee became covered with pollen as it worked the flowers.
The pied hover fly is common throughout the Northern Hemisphere. It is a staple of summer flower watching. Yet, this is the first time I can recall seeing one festooned in pollen.
Our summer residents include two species of bluebirds: mountain and western.
An April posting delighted in views of the Mountain Bluebird. We are near the centre of its breeding range, so we see both those that are migrating past us as they head farther north, and those that stay here for the season.
We are near the northern edge of the breeding range of the Western Bluebird. This means that we see fewer of them, but those that come are here to stay and breed.
Fans of both species of bluebirds offer them nesting boxes as incentives for them to stay, and one of these provided the setting for these shots of a Western Bluebird couple attending to its chicks.
The Western Bluebird is plumper than the Mountain Bluebird. But unlike the latter, its indigo blue is accented by a rusty breast and back. This male has brought a bug to feed its chicks. Bugs might be caught on the ground or in the air.
The female Western Bluebird has more muted colours. This one has brought a grub for her chicks, but she first flies to a spot adjacent to the nest, apparently to check for watching predators, before making the revealing flight to the nest. Her left leg shows that she has been banded.
There are almost endless comings and goings throughout the day as each parent ferries food to its chicks and removes faeces. Here the male bringing a bug has to wait while the female removes a faecal sac. This aspect of bird parenting is reminiscent of diaper changing. Previously, I have shown this behaviour with the nuthatch, both dipper and swallow, and the robin.
“I’m off to find more food for my voracious chicks — this is really endless.”
Four months ago, I posted a picture of a hawk in the genus accipiter and turned to my readers to help identify it. The sentiment was that is was a Sharp-shinned Hawk, rather than the larger Cooper’s Hawk (the other likely choice). The problem has occurred again, but this time I managed a much better picture or two.
This time, the accipiter is a juvenile, and once again, I think it is a Sharp-shinned Hawk, but I can see conflicting evidence in that while the tail looks like the sharpie, the breast looks like a Cooper’s. So, I am at the mercy of those who are willing to comment.
When spotted, the hawk was hunting from a fence post.
It soon flew off, and so allowed a different view.
The Trillium is an early-spring flower of the deep forest, which is based on the number three: It has three leaves, three sepals, and three petals. Our local trillium is known variously as the Western Trillium, the White Trillium, and the Trillium ovatum (for ovō meaning to rejoice or applaud, as in ovation).
Most trillium petals are whitish, as one name for the flower suggests. But, now and then one sees pinkish or even markedly purple petals. These are just the white petals that have turned this colour as a result of anthocyanins.
Anthocyanins are pigments that provide the characteristic colour of red grapes, cabbages and beets. However, anthocyanins are also antioxidants and some plants make them to deal with the stress of either cold (T < 10 °C) or aging. It seems that the purple of the trillium petals is just a side effect of a device to protect plant tissues.

The Red-winged Blackbird is common year round to the south, but seasonal here where the arrival of its bubbly song heralds the return of spring. They are then mainly found around marshes where they eat seeds and insects.
The bird is named for the male, which is indeed black with red (and yellow) epaulettes.
Females are a streaky brown, more reminiscent of a large sparrow.

The goslings finally hatched.
Three weeks ago, I posted a picture of a goose sitting on a nest. Since that time, the nest has been frequently checked from a distance to see if the goslings had arrived. During all that time, the gander stood guard, ready to fend off intruders. Meanwhile other families of geese swam by.
The abiding question was: Will our goose succeed in hatching goslings or not? This remained uncertain until two goslings appeared yesterday morning.
This is the goose on the nest taken three weeks ago.
During the long incubation, other families swam past with from two to six goslings. If it is possible to read frustration and envy in the face of our gander, it was at these times.
Finally yesterday at noon, the new parents were seen with their two goslings.
