Snuggled up

It's late winter in Canberra with frosty nights and sunny days, and the birds are beginning to show springtime behaviour. The Tawny Frogmouths are drawing closer to their breeding sites, moving in from more distant perches to be close to their nest sites. They will be building their nests soon. Although none have started to do so yet, I have seen birds with well-built nests by this date in previous years, with the earliest eggs laid on the 12th August. Meanwhile, they are making the best use of the sunshine as they roost during the day.

They are medium-sized birds, about the size of a Tawny Owl, and live mostly on invertebrates. However, they have a slow metabolism and as insects and such creatures are not abundant during winter, they move as little as possible, slow down their metabolism even further and sit in sunny situations, all to conserve energy. And to do so while daytime predators are about, they have evolved excellent camouflage for protection.

Yet, they don't stay completely motionless all day. This pair mostly roost farther along the branch towards the trunk, but as the sun has crossed the sky, they have shuffled along the branch to stay in the sunshine. Today was cold.

The spot where these birds usually sit is farther to the right, as can be seen by the worn red bark on the branch and a fluff of cast down below where they normally sit.

The frogmouths sit fluffed up and huddled into a rounded shape to keep warm, and by snuggling up close to one another the pair gain extra warmth.

Scottish Top Ten 2015

I have now returned from my field-trip to Scotland and have a few thousand photographs to catalogue. So it is time to reflect on what I achieved work-wise and image-wise. I thought the first thing I should do is pick out a top ten selection of photographs. These are not necessarily the best photographs, in quality or technique, but they are the ones that I consider as capturing the essence of my days in the field, the places I visited and the wildlife I saw.

And now that I have posted them I have already thought of others which could just as easily have fitted the bill.

Ptarmigan on the rocks



I was up in the Cairngorms surveying ptarmigan last week, Rock Ptarmigan Lagopus muta, and they are well named for they are seldom seen far from rocks in the Scottish hills.

Their breeding season was about two-three weeks later than usual this year due to prolonged and extensive snow-lie. Many of the birds did not have any chicks, perhaps after failing to lay eggs or losing eggs or young? Others had very small broods of only single chicks compared with the usual average of  five or six chicks of about two weeks age - the age of the chicks that I did see.

Several hens which had no young had joined cock post-breeding moulting flocks and were roaming through the boulder fields skulking quietly amongst the rocks. When moulting, these birds typically prefer to walk away from any intruder as they probably feel more secure doing so while they have some flight feathers missing or only partly-grown.

They seemed so at home in the boulders, hopping and skipping over them with no effort at all. At times they were running over what to me was very awkward ground to walk over. They run over any open ground or large open slabs as they feel exposed to predators, then slow down once secure amongst the jumbled rocks again.

I left them to it and watched a snow bunting for a while, singing from the top of a large boulder. And in the meantime the ptarmigan settled down to rest amongst the rocks, disappearing to my eye as their colours blended with those of the lichen-covered boulders.

Wild Assynt

The jagged ridge of Stac Pollaidh

While surveying birds in the Highlands, one the extra joys is the magnificent hillwalking that, well just has to be done in such stunning scenery.

Pillars abound in these sandstone hills

I was in the Assynt hills last week and grabbed the best day of the summer for a great walk over one of these relatively small hills. They might be small, but each hill in the area has its own particular character and they pack an amazing variety of landforms into this quiet corner of the north west Highlands.

There is so much to explore, around every corner or over every bluff that I don't need to describe where I went. It's all great fun. One of the best experiences in walking these hills is to discover their secrets for oneself. There are landscape-scale features such as the impressive peaks, but take time to look at the finer lines, the hills are covered with little details which mirror the grander features.

A golden eagle added its shadow to the landscape

Then to add cream to the scene; I was walking along a ridge, carefully watching my feet, when a shadow drew over my path. I knew straight away that there was an eagle above, what else could have cast such a shape. And sure enough, I looked up and there was an adult male eagle displaying in deep dives as it cruised along the updraught from the ridge.

The day was already one of my best in the hills this year, now it was probably the best.

Suilven in the evening light

I stayed in the hills til evening, watching the rocks change colour in the sinking west coast light, until I had to finally turn my back on them til next time.

As ever, the trick to any good day is to be there, be out there, do something, do anything, then every once in a while a special day comes.

Golden Eagles Fledging

A Golden Eagle Aquila chrysaetos eyrie set in a large Scots Pine

It is now time for golden eagle chicks to leave their nests and I have been checking several sites to monitor their breeding success. The birds usually fledge in their tenth week, which is a long time for any bird to sit out as it slowly grows, filling in the hours, days and weeks watching the world go by between occasional feeds and long sleeps as it develops from a tiny downy chick to a sturdy eagle.

The adults began nesting in March, laid their eggs at the end of that month, incubated them for six weeks, and now will have to still provide food for the fledglings for a few months. So most of an adult golden eagle's year is filled by rearing young.

This eyrie was built in a multiple fork in the tree, a massive tree with a wide trunk and a magnificent spreading crown
- a true forest giant  

The fledglings' first flight can be a wobbly affair, and this bird will likely take a short one to a neighbouring tree branch. I was surprised that it hadn't taken that step as it was so well developed, but is was raining that day, so perhaps it was waiting for the best flight conditions for that important stage of life. Other birds I have checked lately have left the nest, one twin had gone off around a corner and was nearly a kilometre away from the nest, yet it's sibling was still in the nest - but testing its wings with big strong thrusts and hopping about the nest.

There will be young eagles jumping from trees and cliffs all over the Highlands this week, what a thought, but they will have testing times ahead.

This eyrie was a few metres wide and although the bird is fully grown size-wise, it can be distinguished as a chick by the bright yellow cere and base to its bill. Adults have less bright bills, they are more generally grey-coloured.
