Small Sea Birds Hold Heat Rather Than Cranking Up the Furnace

Source: ScienceDaily (May 2, 2011) —" A new study offers some clues about how small aquatic birds survive in extremely cold climates. Staying warm is hard work for aquatic birds. Heat loss is around twenty times greater in water than in air, so aquatic birds have to increase their resting metabolism to generate heat on the water. Heat loss is an even greater issue for small birds, so it was assumed that small birds would have to increase their metabolism in water even more than large birds do..."

ScienceDaily (Feb. 10, 2011) — "Up until now it was unknown whether males of the great bustard (Otis tarda), an emblematic bird in Spain and endangered at a global level, transmit information on their weight, size, and age through their plumage. For the first time a study shows that the 'beards' and the design of the neck are "reliable" indicators of the weight and age of their bearers, and are used to both avoid fights with competitors and to attract females..."

This is a target I have set myself. To my knowledge only the legendary Ian Sinclair has done it before and publicly announced it. Will I do it? I don't know, but I am going to give it a damn good go. My past achievements with this in mind are as follows:

2008: 701 birds - target was 700, achieved with a 6 day dash around the country to get the last 12 birds. #700 was Pygmy Falcon near Prieska. An Orange River White-eye topped it off at 701.

2009: Target: see 800 birds over 2 calendar years. Total achieved for 2009, 744. Total achieved for the two years, 814.

2010: Too busy, birded Choma for the Chaplin's Barbet, Uganda for an expansion on 2 days birding done in 2009 when on a business trip, and Debbie and I visited Peru for another mind blowing visit plus an expansion of my South American bird list (in one country) of 570. Somewhere in the late 600's achieved on the year list in Southern Africa.

2011: THIS IS THE YEAR!

Now I could not do all of this for no reason other than getting a good year list for myself, so I have been in contact with Birdlife South Africa, who under the current leadership of Mark Anderson, are doing truck loads for bird conservation and awareness in our country as well as further into the region. My effort needs to be focussed, and to this extent I have chose the White-bellied Bustard project as the beneficiary of donations received.

The funds will go to Birdlife South Africa, and in particular will be channelled towards the White bellied Bustard project. Barrow’s Korhaan as “our” bird is known has been lumped with White-bellied Bustard, a bird more widely spread in the continent and touching our region in the Kunene River region of Nambia. Our particular bird, Eupodotis senegalensis barrowii is listed as Vulnerable on the Red data list, whereas the broader African population is listed as Least Concern. With all the threats and recent publicity in particular of hunting of Bustards in our region, it is important that we establish as much information as possible on the various populations of these birds. The public’s donations will assist in providing funding for amongst others, DNA analysis and satellite tracking of the birds. The tracking will help establish movement in the breeding and non breeding season, as well as monitor habitat use of pristine vs agricultural land. To give an idea of why this bird is becoming so endangered, as little of 2% of the extremely over exploited grassland biome is formally protected.

In my effort to achieve my target of 800 species, I intend to broaden awareness of birdlife, the bird’s plights, their benefits to the local communities in terms of bringing in eco-tourists, as well as in general the joys of the hobby of bird watching.

I have opened a 32 day notice deposit account, which will accumulate funds over 2011 and be formally handed over to Birdlife South Africa early in 2012. The details of this account are:

Account name: ND Perrins
ABSA Private Bank
Account number: 9256319602
Branch code: 632005
Account type: Savings

Should anyone like to nominate their favourite bird or a bird number on my list, they can email me that, and it will be linked as such on the website as it grows through the year. A list of donors will also appear on the site. My first donor was an American birder I met last March, who opened the proceedings with a $100 donation, and nominated bird # 745 to have his name against.

In order to maintain accountability, it is preferable to put your name as a reference when depositing or transferring to this account, alternatively if you wish to remain semi anonymous, your ID number. I would like the account to be fully auditable by Birdlife South Africa should the unlikely need ever arise.

So please all of you dig deep, think of the birds and those poor Bustards, and happy birding in 2011!

Cheers for now, and watch this space.

Niall.

Tick tick tick.... year counter on 375... Ovambo Sparrowhawk added this morning.

Just to let you know what a wonderful start I had to my big birding year, I awoke on the 1st of Jan, ready to see which bird would be #1. And there he was, calling away, right above my tent!
