Hills

For the first week of my trip I went across to the west and climbed several hills, part for fun and part of study where ptarmigan live, which habitats, over what bedrock etc. I based myself at the KingsHouse in Glen Coe from where the morning view was of the Buachaille Etive Mor, perhaps the finest-shaped hill in Scotland.

I had some great days out on these hills, in sun, and cloud, but no rain or midges. The view below is of the fine ridge climbing up to the summit of Sgorr Dhearg on Beinn a' Bheithir.
Another hill I went up was Beinn Sgulaird in Appin, above Loch Creran, where I found a female ptarmigan sitting on her nest and nine eggs - a large clutch for the western Highlands and an indication of good quality food on the base-rich bedrock in the area.
Long-eared owl chicks

I am in Scotland for a few weeks and one of the first things I did on arrival was go out in the evening with my brother to ring some long-eared owl chicks. These birds nest in old crow nests, set in dense conifers - sitka spruce in this case. Nice and dark under the canopy for the owls to hide in during the day. The chicks have big orange eyes and the beginnings of their ear tufts. At this age they are highly mobile and can easily clamber around the nest tree branches.

Bright Eyes

Last weekend I was mist-netting birds at Mongo National Park with Anthony Overs. Two of the species we caught struck me as having wonderfully coloured irises. The Eastern Spinebill has a fire-engine red eye and the Lewin's Honeyeater a soft-tone blue eye. These are both forest-living, small passerine species. Their eyes are so tiny, yet these birds must have fine perception to pick out such tiny detail. As birds see a different spectrum from us, what do they see when they look into each others' eye?

Autumn Pond


It is autumn now in Canberra - a very fine time to be there. The above photograph received an honourable mention in a recent fun photography competition ran by the local radio station ABC 666 - the judges loved the images, and the stories sent in with many of the pictures. My image is of a sculpture in Commonwealth Park, set in a small pond surrounded by non-native deciduous trees, which add the colour. I inverted the photograph to show what I see when I look beyond the obvious straight image.

Lord Howe Island

I have just spent a week on Lord Howe Island; birding, walking and snorkeling. The snorkeling was wonderful; easy as there are bays or lagoons on either side of the island so there is always somewhere to go unaffected by the wind.

The Lord Howe Island woodhen which was once restricted to breeding on the summits of the high hills can now be met foraging around the picnic spots on the headlands - a measure of the successful breeding programme.

The summit of Mt Gower is often covered with cloud/mist forest and epiphytes such as these orchids are abundant. Out at sea is the striking rock of Ball's Pyramid.

Mt Gower is also the main centre for the breeding providence petrels which breed only on Lord Howe Island. Tens of thousands nest in burrows and they can be called in, landing with fluttering wings at one's feet.

Providence petrels continually fly around the sky between Lord Howe and Ball's Pyramid.
Most of the birds had finished breeding for the season while I was there, although there were still large chicks in a some of the red-tailed tropicbirds' nests. I could spend hours watching these marvelous birds from the cliffs of Malabar hill.
