Scotland’s first full humpback whale post mortem for Mull’s first stranding of iconic species

Recovering dead Humpback Whale
Recovering dead Humpback Whale
Scotland’s first full post mortem of a humpback whale – found dead at Fishnish on the Isle of Mull this week – was carried out yesterday by veterinary pathologists with the assistance of conservation charity Hebridean Whale and Dolphin Trust.
 
The seven-metre, eight-ton animal – believed to be the first humpback whale ever to strand on Mull – was discovered floating close to shore on Wednesday 25 June, and was craned out of the sea the following evening. The male calf had not recently been feeding and was probably still dependent on its mother.
 
Hebridean Whale and Dolphin Trust’s Science and Strandings Officer Dr Conor Ryan, who is an expert on humpback whales, assisted with a post mortem examination with veterinary pathologist Andrew Brownlow of Scottish Rural University College to establish the cause of death. Preliminary results from the examination were consistent with drowning, although the cause is unclear.
 
“This highly unusual and sad discovery is a reminder that Scotland’s west coast waters are extremely special and host a great variety of

Ltl Acorn 850nm, 940nm, 24 and 44 Infra Red (IR) LED arrays compared.

Fig 1:  5210A with 24 IR LED Array
Following on from my previous post which compared the FOV of the new Ltl Acorn 5310 standard and wide angle lens models, this post illustrates the differences in appearance and performance between the old and new infra-red (IR) LED arrays.

Up to now all the Ltl Acorn camera models have used a 24 LED IR light source as shown in figures 1, 2 and 3. Figure 1 shows the 5210A with 24 blue LEDs which emit light in the 940nm wavelength. These LEDs are covert and do not glow when operating.

Figures 2 and 3 show the 24 LED 850nm and 940nm versions. The white LEDs emit light in the 850nm ( nanometer ) wavelength and can be seen to glow red when viewed straight on during operation. They are visible up to 10 plus meters distance and although the IR light emission has double the range of the 940nm version they are not suitable for use in situations where the camera may be vulnerable if observed, such as security applications.

Acorn have now released their 5310 series cameras using their newly developed 44 LED array which doubles the night time light

A new annual week-long festival boosting the profile of The Hebrides as an internationally-important hotspot for whale spotting and conservation action will be launched on World Oceans Day on 8 June, in what is believed to be the first event of its kind in Scotland.
 
Humpback whales, orcas and bottlenose dolphins will take over Tobermory on the Isle of Mull between 8-15 June 2014, as conservation charity Hebridean Whale and Dolphin Trust (HWDT) celebrates its 20th anniversary with its

New Ltl Acorn 5310 series cameras - Standard and wide angle lenses compared

Fig 1: Ltl Acorn 5310A with standard lense

My apologies for the lack of technical posts and reviews over the last few months but I'm just emerging from what I think of as the lost winter. Late last year a nine year old hernia suddenly became much worse and prevented me from doing any more than essential tasks. Restricted walking and no heavy carrying meant I couldn't do winter camera surveying which was a great disappointment and sitting at a computer or workbench for any length of time was not possible.

I eventually had an operation in early February following which I am only now becoming properly active; and still catching up on camera repairs.

Anyway, enough of all that and on to the subject of this post which is a comparison of the standard and wide angle lenses in the new Acorn 5310 trail cameras.

The 5310 also has a larger 940nm IR LED array which doubles the night range to over 60 feet (20 metres) when compared to the 5210 and 6210 cameras at 30 feet.

Figure 1 shows the 5310A with the standard lense and Figure 2 shows the 5310WA with the wide angle lense. Apart from the

Unique community purchase go-ahead for Highlands pinewood restoration project

Loch Arkaig
Plans for a major new pinewood restoration project in the Scottish Highlands have been given the go-ahead after Forestry Commission Scotland agreed to sell 1,086 hectares of woodland at Glen Mallie and South Loch Arkaig in Lochaber to a Highland community group in partnership with conservation charity Trees for Life – marking a major milestone in efforts to restore the ecologically important but rare native Caledonian Pinewood habitat.
 
The Achnacarry, Bunarkaig and Clunes (ABC) Group and Trees for Life now have 18 months to raise £500,000 to buy the land, following which they will begin a process of native woodland restoration and of restoring the links between the local community and the wild and remote country on the south side of Loch Arkaig in the West Highlands.
 
This is believed to be the first time that a conservation charity has partnered with a community group to purchase surplus Forestry Commission land under the National Forest Land Scheme. The scheme – administered by Forestry Commission Scotland – gives communities and non-governmental organisations the opportunity to acquire state-owned forest land which has

London cyclist Timothy Judge has set himself the arduous challenge of cycling 5,000 miles in 2014 to raise funds for conservation charity Trees for Life and its restoration of the ancient Caledonian Forest in the Scottish Highlands.
As part of Tim’s epic bid, on Tuesday 20 May he will set out to cycle from London to Dundreggan Conservation Estate in Glenmoriston near Loch Ness. He aims to complete the 600-mile journey in six days – arriving at Dundreggan for Trees for Life’s 25th anniversary celebration open day on Sunday 25 May.
The event at Dundreggan – Trees for Life’s flagship project and a 10,000-acre biodiversity hotspot – will include guided walks to explore ancient woodlands and spot wildlife, opportunities to meet and feed wild boar and learn about their role in restoring the forest, the exclusive launch of Trees for Life’s 'Forests of the

Surveys show need to conserve western Scotland’s healthy seas

Research surveys conducted by the Hebridean Whale and Dolphin Trust (HWDT) during 2013 have identified a remarkably wide range of whale, dolphin and porpoise species – highlighting the need to conserve the rich biodiversity and globally-important marine habitats in western Scotland’s seas.

The latest research is part of HWDT’s unique and long-term monitoring project of cetaceans – whales, dolphins and porpoises – in the Hebrides. With growing concerns over the state of the UK’s seas, and threats to wildlife and ecosystems from human activity, HWDT is calling for volunteers to help continue the pioneering research in 2014.

In total during 2013, HWDT recorded more than 400 encounters with cetaceans and basking sharks, and made almost 1,000 underwater detections of cetaceans using specialist listening equipment.

Kerry Froud, HWDT Biodiversity Officer, said: “The impressive range of species of cetaceans and basking sharks that we have documented this year highlights the wealth of marine life in Scotland’s west coast ocean environment – and the importance of ensuring the continued

This web site is about the wildlife, particularly the mammals, of the Glen Affric National Nature Reserve area in the north west Highlands of Scotland, UK; and the equipment I use to search for them, which is chiefly trail cameras.

I provide a technical support and parts service for the Ltl Acorn range of cameras and the income from this provides for the upkeep of this site and the purchase of cameras for my own surveying.

I hope you find the site useful and informative; and please contact me if you have any questions that I haven't already covered.
