Greenshanks

Double-red back on his feeding-lochan
I have spent the past few weeks studying Greenshank in Sutherland, in the northern Scottish Highlands, where I soon found the bird colour-ringed with double red, which was caught three years ago at the same site. He has also been seen since on the same wintering grounds in Suffolk. So he is very site fathfull for breeding and over-wintering.

This study is a cooperative voluntary one, done by a few members of Grampian and Highland Ringing Groups, with the aim to determine where Greenshank which breed in northern Scotland overwinter. But first we have to find the birds on their breeding grounds by searching the lochs for feeding birds and the moors for nesting birds. They are notoriously difficult to find.

Long-tailed Tit nest

It has been a long cold spring in the Scottish Highlands this year, with the trees late in coming into leaf. Any birds which nest early, therefore need to be crafty in concealing their nests from predators. Long-tailed Tits, are masters of this. They build their domed nest with mosses and then dapple the surface with flecks of lichens gathered from the branches of neighbouring trees. The finished surface then blends in almost imperceptibly with the lichen-covered nest branch.

Here an incubating bird watches from the entrance hole to the nest, set high on the right side. Even her face seems to merge with the colours of the lichen on the branch. In all, a marvellous example of camouflage.

Spring at last

Birch catkins and fresh leaf buds
I have been in Scotland for over two weeks, and at last Spring has arrived, about four weeks late.

Rowan leaves open as last years berries wither
There have been cold northerly winds most of the previous weeks, with some strong westerlies bringing in wild rainy weather. Then after a particularly heavy downpour yesterday, today woke up to still, quiet skies and later a warm sunny afternoon. The leaf buds and catkins on the trees responded to the warmth, bringing bright green foliage into the landscape.

Wall Flowers

The front cover of the current edition of the Leopard magazine is of one of my images from a feature inside written and illustrated by me on urban plants: describing how they colonise various niches in our cities, adding colour to otherwise drab decay.

Autumn Frogmouths

Tawny Frogmouths can be very difficult to see when roosting quietly up in the branches
We are well into autumn in Canberra now and the Tawny Frogmouths are even more tricky to find than in spring or summer. They can be anywhere in their home ranges, but this adult male and juvenile were still within a hundred metres of last year's nest. I couldn't find the adult female. I had expected the youngsters to have left their family groups by now, as this is often the time of year when resident birds establish or confirm their pair-bonds and territories. I thought I would find the birds in their favourite winter roost by now, the ones which are better exposed to morning sun and out of the cold south-west wind. This branch was in the sun, but higher up, about 15 m,  and more hidden than the winter roost.


The adult male, on the left, sits comfortably, partially fluffed up as he basks in the sun, while the young bird is a bit more secretive, taking on a partial branch-pose for camouflage. The adult bird has seen me many times before, so is probably less afraid of me.


The young bird is identified as such by her scruffy moustache and eyebrows, and her nasal bristles are not as finely developed as those of a bird in full adult plumage. She is definitely a  female as she has taken on a rusty colouring to her wing coverts. Males are more uniform grey.
