Squawking gulls and cranky crows are a sure sign of trouble. Moving briskly west on the seawalk below my Vancouver cottage, I was focused on using my Nordic poles to pick up the pace of my early morning walk. The idea was to extend the stride of my step and the length of my arm pull to enhance the benefits of the walk. But the noise of the seagulls and the crows diverted all my good intentions and I stopped to see what was the matter.
Sure enough, at the water’s edge where the tide was retreating from the rocks coated with kelp and rich green algae, a bald-headed eagle was standing on the biggest stone around. Not as large as others I’ve seen, his shiny black feathers and snow-white head still stood as a beacon to the eyes. He stood there as if glaring at the hoards of smaller birds advancing towards him.
At least three large well-fed gulls and three more black crows took up positions around him, all squawking madly as if in a fit of frenzy. A couple of gulls approached, flapped their wings and swooped just above him. Then two cocky crows dive-bombed him from two different directions at the same time. They repeated these actions over and over. It all appeared as a well-choreographed attack, perhaps to protect the favoured feeding grounds of the smaller birds. Eventually, the eagle lifted his large wings and flew away across the bay and high in the sky, the crows and one seagull in hot pursuit.
It occurred to me that this may be an example of allied interspecies coöperation against a common enemy. I would have to ask a naturalist about that. As a friend and I had seen a similar incident about the same time yesterday morning, it probably is a daily ritual at a particularly rich feeding site on the shore.
Still later on the seawall, I narrowly avoided being hit by a snail-shell dropped by a crow descending over the sidewalk onto the rocks. As there was a live snail inside, we threw the snail onto the seashore for the crow to recover. Alas he was two slow. Another crow which I had not seen must have been watching and waiting. Just as soon as the snail hit the sand, the second crow was on it for his breakfast.
Later on this same walk, I spied a tall heron fishing in a shallow pool between the rocks. He was standing silently and stately, moving slowly and stealthily in search of his food. A bevy of gulls and Canada geese grazed nearby, and a squadron of crows sat on a log watching over the scene. Obviously, these birds coexist peacefully. I guess only the bald-headed eagle is considered a threat.
Update on the litigation between CN Rail and the District of West Vancouver.
In February 2017, I published a post describing CN Rail’s efforts to have the public using the seawalk declared “trespassers.” Their aim is to monetize to the maximum whatever leasehold interest they can enforce against the District. Diane Powers, spokesperson for the District, advised me last week that the Canadian Transportation Agency held a two-day oral hearing in October 2017 on the District’s application for a declaration that it has a “right of way” on whatever the interest held by the railroad. The CTA agreed that they had jurisdiction to deal with the issue but adjourned their decision until the British Columbia Supreme Court ruled on the earlier lawsuit started by CN alleging that the public were “trespassers.”
Ms. Powers told me that it may take another three to five years for the matter to be concluded. In the meantime, the District has refreshed notices to the public indicating that so long as the litigation is ongoing, the District can only do maintenance on the seawalk that affects health and safety. They can change lightbulbs that affect lighting, remove trip hazards, and engage in any storm cleanup. “Cosmetic maintenance” is suspended for the duration. The gardens at 19th Street and 24th Street that mark the boundaries of the seawalk, and the narrow green areas at 21st and 22nd streets, are designated park areas at the foot of District streets. The District will still tend to them. Like most North Shore residents, I have a visceral personal interest in this dispute, and will monitor what happens.
