I knew the
easterly wind would try its best to blow me out of the tree. It howled
across the shrubland with enormous force as I pushed my way through the
entangled wattle thicket toward the nest. The raven was very well
hidden, except for a few tail feathers which protruded above the basket
of sticks, telling me it was incubating. As I discarded my shoes for
much sturdier, comfortable bare feet, the wind roared across my
eardrums. It’s strength increased with every metre I pulled myself into
the low Flooded Gum. WHAT a breeze!
The nest was only about 6
metres up. I was nearly under it when an enormous gust sent the trunk
bending sideways. My adrenalin was pumping softly, keep me focused but
not frightened. Another huge burst of air, the leaves swished against
me, as though like clutching fingers they sought to rip me from the
trunk. The wind dropped slightly for a moment and I stood, stretching
upward with the camera, pointing it downward at the nest and snapping a
few shots. One. Two. Not the right angle to even think about using the
viewfinder. I hadn’t seen the incubating bird fly off but this didn’t
surprise me. Any feathered animal flapping up would be carried a hundred
metres sideways in seconds!
I could feel another gust
coming; it had been ‘still’ for too long. I slunk into the fork
supporting my feet, folding up like a Koala. Whhiiieeeeeeeewww! A
massive gust hit me, sending the whole trunk lurching over like a piece
of rubber. It was like being on a bucking bull with the fieriest
attitude! The gale persisted and I swayed around, clinging on for dear
life. I had several thoughts of the tree-top snapping off, sending me
plummeting downward with it. Although I wasn’t that high, it would still
hurt.
It
was difficult to see into the nest in the first couple of photos, but
eventually I managed to grab a shot which revealed the contents.
The above picture shows a typical clutch of eggs laid by the Australian Raven (Corvus coronoides).
They are nothing short of beautiful, one of the prettiest eggs of all
Australian birds. July is the month when this, one of our earliest
breeding songbirds, begins to nest. In the Perth hills, ravens (and NOT
crows, as they are often mistakenly called) are a common songbird. Their
usual clutch is 4, but I will never forget the first nest I discovered
at the age of 16 which contained 6. The eggs are laid inside a deep cup
which is almost always made of carefully woven strips of bark. Ravens
collect bark directly from tree trunks and tear it into strips with
their beak before adding it to the nest. Occasionally you will find bits
of man-made fibre too, like the blue twine in the above photo. The
raven’s cozy cup forms the inner lining of the large stick nest, a bulky
structure which is normally conspicuous at the very top of the tree.
Every time I see a nest belonging to this species, or the closely
related Little Crow (Corvus bennetti; -
which is not found in Perth), the term ‘crow’s nest’ pops into my head.
The platform at the top of a ship’s mast is a fitting analogy with the
real thing.
Despite my battle with the
wind, I was happy to scale the tree as it was lucky to find a raven’s
nest less than 10 metres off the ground. In the Perth hills the species
normally builds in a fork over 20 m high, often at the top of a very
tall Marri tree. Today’s Flooded Gum on the sandy Coastal Plain north of
Perth was much lower, but in any case ravens like to have a good view
over the habitat surrounding their nest. This is presumably to see
intruders (like me!) approaching, allowing a fast getaway.
After
snapping a dozen photos, I thought I’d better quit while I was ahead,
so I slid down the tree-trunk like a fireman. Another nest, another
thrill, another wonder from the natural world. There’s nothing like
climbing to a nest in the top of a gum tree.
