Well I tend to be an early riser, up about you know, six
usually, and this time of year, summer time, in Connecticut especially very
good reason for being up early. Because
I remember when looking for a home here coming across the description in the
realtors catalogue of this property that we finally bought, it said two
thousand three hundred feet of waterfront property. And by golly it is amazing! Because although most of it is absolutely
unusable, in that you know, it’s steep wooded forest going down to the lake, it
nevertheless provides a fabulous habitat for all sorts of animals. And when you’re out early in the morning, we
can go down to the lake, down to the dock, sit on the dock and actually if
we’re very quiet and stay there for a while, sometimes you’ll see deer come
down to drink form the lake, and it’s really quite magical. And sometimes the ducks come by as well and I
actually came across a book recently on bird watching. Now I’ve never really had much interest in
bird watching, I’m happy birds exist, I like to see them around, but that’s
about it. But I happened to open this
and I was flicking through it and there was something that was really striking
to me, it started to tell me about why birds are different colours, in terms of
how colouration is so important for their protection. Well obviously you know, you figure that
birds have to use camouflage as most animals do and indeed a bird’s survival
often depends on its ability to conceal itself, and especially of course
females sitting on their nests. So
there’s this thing called cryptic colouration or protective colouring, which
means the birds, if still, virtually disappear.
So here’s something that I think is kind of fascinating, when you see
birds with streaked or striped feathers, you can be pretty sure that they live
in grassy areas and that’s because the appearance is concealed, because the
field grasses blend in with the colouration.
On the other hand, birds that have green feathers are likely to be up
there in the tree tops and if they didn’t move around so much, you’d never see
them- the green matches the leaves. And
then there are the birds with dark backs and light bellies, like sparrows for
instance. And you can be pretty sure any
birds like that spend a lot of time on the ground, because the light underside
breaks up the overall shape of the bird, so it’s less noticeable, whereas an
all dark bird would be far more easily visible.
And of course you know the mottled grey or brown feathers of say an owl
that mean that birds just blend into the bark as long as they don’t move.
So, suddenly I had this set of distinctions about ahh we can
really understand different kinds of bird colouration here and what kind of
habitat they probably inhabit. And for
me anyway, this was like making sense of something which previously had been
you know, pretty random. And I often
think that when we can do that, when we can understand some working principles,
things become both easier to understand, but I think often more fascinating as
well, because it’s not just I don’t know, there you go, it just happens to be
pure chance- nothing very chancy about evolution in one sense, because it
really is about how you ensure your survival.
So I don’t know whether I’ll be going in for any cryptic
colouration myself, I don’t think that’s necessary. But just looking around the world and
understanding it differently, has enriched my morning experience as I sit on the dock and enjoy a cup of tea and look
up in the trees and see the birds.
So ‘til the next time.
