    Reliable Trail Cam wanted

    Thanks for that information; now I know why every one of my Browning cameras has been malfunctioning after 2-3 years and suddenly failing to record the correct date and time, thereby losing me vital data and totally screwing up my research! It's really infuriating, as otherwise they are handy...

    Best book to get into bats and bat detector in Europe

    I would suggest building up your knowledge and identification skills using the following books: Russ et al. (2021). Bat Calls of Britain and Europe: A Guide to species identification (Pelagic Publishing) Barataud (2015). Acoustic Ecology of European Bats (Biotope Editions) Runkel et al. (2021)...

    Schreiber’s long fingered bat. / common bent ring bat

    Are you using the Echo Meter Touch recorder and basing the ID on the auto-ID feature? If so, then unfortunately I wouldn't pay the auto-ID much attention. In Bulgaria where I am using my Echo Meter Touch Pro for some research I am finding the vast majority of auto-IDs totally wrong when I look...

    Bat detector choice???

    That's strange. I haven't had any connection problem. I carry mine around recording whilst I walk transects all over mountainsides and haven't ever had it disconnect. The USB connection for me is firm and snug.

    Bat detector choice???

    I have owned an Echo Meter Touch 2 Pro (from Wildlife Acoustics) for a number of years now, and use it for my bat research in Bulgaria. The Echo Meter Touch 2 Pro offers Auto ID for European, North American, Neotropical and South African bats. However, I have found the auto ID is very...

    Bat in Southern Morocco - Feb 2020

    You are right; I hadn't checked the locality of your recording. It seems to be too far south for Common Pipistrelle. In Europe, the end frequency of Kuhl's Pipistrelle tends to be in the 35-40 kHz range, and the calls on your spectrogram are above 40 kHz, so I ruled this species out. However...

    Bat in Southern Morocco - Feb 2020

    Based on the spectrogram it looks good for Common Pipistrelle, with the minimum frequency dropping down to just above 40kHz. As John says, Ruepelll's Pipistrelle wouldn't drop so low, typically staying above 50 kHz. The minimum frequency for Savi's Pipistrelle would normally be lower than 40kHz...

    Birds new to science

    It gets half a page and states: 'It is an enigmatic bird, possibly not justifiable as a valid species; it has been suggested that it might be an aberrant example of Ashy Cisticola or a hybrid between that and Rattling Cisticola, but there are no comparative DNA studies.'

    Birds new to science

    The opening chapter of the book states that the species covered are only those described in publications dated 1960 or later (that is up to June 2015). It also states that splits are not included, with the only exceptions being taxa that were first described as subspecies after 1960, and which...

    Escaped Lynx killed - UK

    There are no recent records of Lynx killing a human as far as I am aware. I posted the following information on the Mammal thread earlier today referring to a review of the data by Löe & Röskaft (2004) of human deaths caused worldwide by large carnivores in the 20th century. I will copy and...

    Escaped Lynx Killed!

    In a review of human deaths caused worldwide by large carnivores during the 20th Century, Löe & Röskaft (2004) report the following statistics: Black Bear: 37 Brown Bear: 313 Polar Bear: 12 Sloth Bear: 48 Coyote: 1 Grey Wolf: 607 (the majority from rabies transmitted to the humans from the...

    Escaped Lynx Killed!

    So its finally happened, the Eurasian Lynx which escaped from Borth Zoo last month has been 'humanely' killed! Apparently it entered a populated area and the authorities decided in their wisdom that the risk to the public was 'severe'...

    What sort of this squirrel?

    Black morph is typically the most common colour form in the spruce and fir forests of central and eastern Europe, since presumably the darker fur colour makes them far less conspicuous and better blend into the darker shade of denser coniferous forests. Red morphs would stand out and be more...

    Wildcats Boca de Huergano

    Hi Steve, Trying to work out the purity of wild cats can be a real challenge nowadays as your photos well illustrate! We are lucky here in Bulgaria, as in the Bulgarian Mountains wild cats remain amongst the purest in Europe. The face of the 'cat' in Photo 3 really doesn't seem to display the...

    A Polish orchid?

    Yes its a very typical native forest floor species in Central Europe, particularly favouring damp places. The other two species Impatiens parviflora and Impatiens glandulifera are introduced invasive species.

    Polish dragonflies

    Yes, definitely Broad-bodied Chaser. The large dark patches in the second photo are diagnostic. Also in you first photo, you can just make out one yellow spot on the flank of the abdomen. However, be aware these yellow marks on the sides of male Broad-bodied Chasers disappear with age, so don't...

    Olive-tree Warbler? Bulgaria

    Very nice photos. Eastern Olivaceous for me as well based on the leg-colour and shorter length primary projection.

    skipper Spain

    The fine spots along the margins of the upper wings indicate that the butterfly belongs to the genus Spialia rather than Pyrgus. The most likely species is therefore Red-underwing Skipper (Spialia sertorius). However, just be aware that recently the genus Spialia has undergone revision, and...

    Wolves kill? - Greece

    To me this sounds very much like an attempt by the local authorities to protect their tourist industry by trying to cover up that there is a real danger from the packs of stray dogs in the region, and to shift the blame onto a wild animal, either wolves or jackals. At the same time, this will...

    Kaleidoscope software

    Hi David, I can't answer your question but just wanted to say I am thinking of buying the new Echo Meter Touch 2 Pro myself for a forthcoming bat survey, so am also very interested in any replies about the Kaleidoscope Software your post generates.

    Hi to Everyone!

    I am a mountain guide and wildlife researcher in Bulgaria, striving to help conserve the flora and fauna of the Bulgarian Mountains. My main focus is research into bears, but to understand the behaviour and ecology of any species I believe it is essential to have a broader understanding of the...
