Nature is wild
and varied, it ranges from the small or insignificant to the large or
magnificent, but within this variety, it could be said that some are better value
for money than others. These species give you rewarding views and behaviour for
very little effort. No need for expensive gear or exotic locations they give
you the very best bang for your buck. Garden birds such as Robins, Blackbirds, and Blue
Tits are obvious candidates and they do offer a lot, but for me, I think the
best value bird is the Grey Heron.
A bird in its prime
One of the things that I feel makes herons
so fascinating is their positively prehistoric appearance, you could throw a
heron back in time to the Mesozoic and it would fit in fine. They. They evoke
the primitive simplicity and subtle predatory instinct of a dinosaur. Herons
alongside cormorants show a great though line in the evolution of dinosaurs into
birds.
Although unwieldy and seemingly clumsy
in flight there is something endearing in the way its broad wings flap lugubriously,
the way the legs stick out backward, jutting out behind it, and the way it
pulls its neck in tight to the body short, is nearly comical.
In Flight |
As a species, they tend to be fairly comfortable around humans. Get too close and they will definitely take flight but keep a safe distance and they are more than happy to just ignore you and carry on with their day. Give them such a chance and they will show you its complete repertoire.
Despite what wildlife programs might
make you think predation observing a successful kill is incredibly rare. The amazing
and dramatic shots of a lion taking down a gazelle represent days and days of
field time and patience camera work. Herons are a voracious species and will
take a range of fish amphibians and small mammals with great relish. Watching a
heron hunt is like viewing a masterclass. Its slow, stealthy deliberate steps
are counterbalanced by its ability to stop stock still. A practiced watcher
will soon pick up on the heron’s subtle skills. The way it cocks its head to
enable it to see through the reflection of the water, the positioning of the dagger-like
beak poised ready to strike.
Catching a vole |
Just by watching the heron’s posture, you can tell at an instant the point it spots its prey. It becomes stiff and stock still, statuesque. If it does move to reposition it does so carefully slowly and with purpose. Finally, its head may move side to side as it focuses and accounts for the refraction in the water and then it strikes with lightning speed.
Caught |
Unlike other predators which often move
to a new location to eat their prey, the heron will usually swallow it there and
then or pad onto the backside. I had the fortune to spot a heron take a fish, a
very large fish, one that it could barely carry. I was convinced that it had
"Bitten off more than it could chew", a case of eyes bigger than its
stomach. But to my amazement, it managed it, and with a great gulp, it swallowed
it down headfirst. You will find most swallowing animals will swallow their
prey headfirst. It makes it easier to
slide down, any spines and the fins of fish all point backward, and of course fish
are streamlined. The heron in question managed its mammoth feat and looked very
full, I could see the bulk of the fish moving down the gullet, what must that feel
like? I think a subtle companion would be a human trying to swallow a cat!
You can find this consummate predator locally on ponds, rivers, and lakes and only watching for a short period of time will give you a great deal of delight and interest. Grey Herons are a top bird.
