Bryo What?

Here we are, the 4th of August already and there just hasn't been much of anything to post about.  Haven't been able to get out on the water for a variety of reasons, seems when it is cool enough (not that it has been extremely hot, but none the less, sunshine on a gravel dike tends to get a bit toasty - especially for little black dogs)  to actually go for a walk over at Harrison Bay, it is so windy there isn't much to be seen.

However, yesterday brought something interesting enough to warrant doing a posting.  A friend was out in her kayak and spotted this.....


in the water.  It was a solid jelly like glob not quite as big as a football, but getting there.  Not knowing what it was, they maneuvered it out of the water and brought it home in a bucket of water....figuring I might know what it was.  I didn't and neither did any number of neighbours who spend a lot of time 'out there' on the water and had never seen anything like it, but with a bit of searching on line it has been identified (and returned to the estuary).  It is a Bryozoa, also commonly known as 'moss animal',
which turns out is an aquatic invertebrate, very tiny (less than .5mm) that lives in a colony, is a filter feeder and completely harmless although apparently they can sometimes clog pipes and things.  There are 5000 species world wide, most in salt water, but some, like this one, in fresh.  They have been around for 450 million years according to what I read, like shallow, warm water and reach maximum size in late summer/early fall and appear to be a recent addition to our area as one online report was about the first one ever found in Stanley Park and the date was 2017 - just 2 years ago! Guess yet another example of global warming at work.

So after that bit of excitement might as well mention the few things I have noticed the past little while....


there is Harrison Bay....your can't see the white caps out there, but trust me,, they are there....one day there were even rollers....it looked like the ocean!  The beach is reappearing.  Osprey nest is now vacated and judging from the number of Osprey flying about, seemed to have been successful.  Noticed a flock of 12 California Gulls flying down the river the other day too - migration is now underway.


lot's of Cedar Waxwing around like this one enjoying the ripening Himalayan Blackberries.  Haven't seen a young one yet but only a matter of time.  Can't seem to venture outside without hearing waxwings.


most Swallows have raised their young now although there was a late family of Tree Swallows the other day, these being two of the four youngsters and Barn Swallows are still feeding young in nests.


I think most of the Bullock's Orioles have begun heading south, not hearing them as much as we were, but this youngster was over at Harrison Bay a couple of days ago.


here at the estuary, water levels are dropping rapidly - this photo was taken 3 evenings ago, water is much lower now, in fact given the warm temperatures forecast for this coming week, I expect we will be able to stand on the grasslands at the viewing tent site by mid week.


Birds are enjoying the shallow water and the muck it leaves behind....caught this Swainson's Thrush having a drink the other evening...


Frequently see the Eurasian Collared Doves either bathing or drinking...


and of course American robins seem to love this sort of stuff.


in our yard and pretty much everywhere else, lots of Black-capped Chickadee families.  One day this past week we had a Red-breasted Nuthatch in the yard....first one in years....was just here for one afternoon and haven't seen it again.

Since we haven't got out on the water, haven't got a definite update on the Purple Martins but I know there has been a lot of over head activity although it is quieting down so my guess is they had another good year and migration will have begun for them.  I have no idea if the new colony off of Kilby beach got used this year.

Hummingbirds, well the male Rufous are long gone, seeing a lot of Hummingbird activity though as the youngsters join the females and the Anna's are taking over again, they seem to lay low while the Rufous are here.

With water levels dropping rapidly and migration underway, who knows, maybe a shorebird will show up one day....it is the time of year when you never know what you might see where or when, so reminder to self - always have your camera with you!
