River otters at Terra Nova pond

The life that salmon sustains

For the last month or so, we've been visiting salmon streams to witness salmon spawning, but have been largely unsuccessful seeing them in smaller streams where I could plunk down a camera. Today, we visited a sunny, but cold and windy Squamish to try our luck there.  The activity by the river confirmed the presence of salmon.

First stop was at Brackendale Eagles Provincial Park. November to December are the best times to see hundreds of bald eagles, feasting on salmon. We were a little early in the season, and we saw few eagles, though the gusty winds might have had something to do with that.  We did see some unexpected visitors - harbour seals.  Here they are, about 5 km away from the ocean.

There were at least three in the water. It was certainly unusual to see them swimming amidst such strong currents.

No need for the seals to steal fish - there were plenty to go around

Caught one!

I'm curious what the mergansers were after...maybe salmon roe trickling past?  Or maybe they're permanent residents, going after small fish that reside in the shallows.

Next, we visited to the Mamquam Spawning channels.  We walked past a golf course to find clear water providing great visibility of the spawning salmon. Most were chum, but I saw a couple of pinks as well.

Went crabbing...technically a success

This past weekend, we took advantage of the summer low tides to take our kids out exploring the muddy beaches.

I had mild ambitions of snorkeling for crab, but with young kids in tow, the best kinds of plans are those that are flexible.

With a spade in hand, we were on the lookout for large holes in the sand. The larger, the higher our expectations, and this hole was as wide as a thumb. We dug down to elbows, yielded this creature, a horse clam.

Inside the clam, we found not one, but two pea crabs.

We've seen pea crabs pretty frequently in larger bivalves, and even in store-bought kiwi mussels. They stow away in the clams as protection.  They offer the clams nothing in return, and may even irritate them in a way that retards the clams' growth, so they are regarded as parasites.  Females will live in the same host for life, while the males (which make up about 17% of the population) will migrate between clams, seeking to mate.

Apparently, pea crabs are fully edible, but it would take even my adventurous tastebuds a bit of coaxing to down one of these.

Here, you may observe the sexual dimorphism between the male (left) and probably gravid female (right).

New Year's Day owling

A dry, sunny day has interrupted what has been a mostly wet week.  It so happens it was the first day of the decade as well, which meant lots of people enjoying a walk on the Dyke Trail on Boundary Bay.  The short-eared owls were also putting on a show...at least a half-dozen individuals prowled the marshes.

Checking out the juvenile bald eagle

No, your monitor's not fuzzy. For some reason, every photo came out fuzzy, at every aperture level, and it's not a focus issue. Yes, this is a cheap lens, but it's the same cheap lens I've always used, and today was worse than usual. I'll have to run some tests to see what part of the hardware is at fault.
