    Goodbye Nature's Home!

    I don’t understand why they don’t offer members a digital alternative. So many organisations do, these days and it is surely a more environmentally friendly way to go. I usually find little to read in it, being generally more style than substance, so a paper magazine is a waste of resources as...

    Your favorite books of 2021

    "A World on the Wing" by Scott Weidensaul. A study of migration and associated conservation issues. He visits destinations including the Yellow Sea (best known for being vital for the spoon-billed sandpiper but also for hundreds of thousands waders including the almost as rare Naumann's...

    Exchange action of Zeiss straps!!!

    This from their website. i did it through a search of their website and didn't follow the email link in case it was a scam https://www.zeiss.com/sports-optics/en_de/hunting/service---support/strap-replacement-service.html quite what this achieves for an item that has already been manufactured...

    Earth's Greatest Rivers

    This program is on BBC2 for 3 consecutive nights. The first, on the Amazon, was excellent, but the second on the Nile was superb. One of the best geography/wildlife programs I've seen. Amongst the many amazing things, the team discovered the extraordinary way in which wildlife has taken over...

    book recommendations: migration + song

    Flight Lines is a lovely book, though it suffers from a baffling absence of maps. You might try Time to Fly: Exploring Bird Migration - Jim Flegg Bird Migration (Birdwatcher's Guide) - Dominic Couzens These have far more illustrations and maps and both can be picked up cheaply in paperback on...

    Eyebrowed Thrush - Helsinki

    I've never seen one grey like that in Scotland. Is it a different sub species to the ones we see?

    Eyebrowed Thrush - Helsinki

    A lady my wife follows on Instagram posted the attached pic and wanted to know what it was. To me it looks like an Eyebrowed Thrush but from what I read this would be a serious rarity in Finland. The lady lives near Helsinki and is happy for me to post it here.

    Hugh's Wild West

    I really like this series. I only stumbled on it by accident and was changing channels when I saw the Dipper footage. The Long Tailed Tit piece in the last episode was also fascinating. The title suggests something rather naff and to be avoided - I'm glad I didn't. It's interesting to compare...

    Dark Lesser BB Gull Scotland

    This gull, photographed at Lochwinnoch yesterday looked noticeably darker and had far less white on its primarys than the local breeding population. I assume that it had migrated from Scandinavia, but can anyone tell me what race it is likely to be?

    Recommendations for North American birds

    It depends on what you want the book for. Sibley is an id book with little other info about the different species. I'm a UK birder and found the National Geographic Complete Birds of North America (ed John Alderfer) interesting, having seen some of the birds. It's a big, chunky book (definitely...

    Warbler ID Bulgaria

    back colour is odd - but could it be a young Orphean?

    New Zealand: Mythical Islands

    Great photography, some very interesting stuff but, yet again dull, dull commentary fails to make the most of it. The program concentrated almost entirely (with the exception of some disastrously introduced species) to endemics, which is fair enough I guess but surely seabirds, especially...

    Digital Zoom

    About 5 years there was a thread on here that concluded that digital zoom was a waste of time and gave nothing that could not be done as well, if not better, by post processing with eg Photoshop. Has anything changed over the past 5 years or is this still the case?

    Super-Powered Owls:Natural World - 3/3/2015 Tuesday BBC2 20.00-21.00pm

    Some excellent information about how owls hunt. Owls are often described a silent fliers, but it was amazing to see how little sound they made in comparison to other species when measured using high sensitivity microphones. I missed a 10 min section in the middle which I need to re-watch. Less...

    Fujifilm Finepix S1

    There seems to be a large variation of opinion depending on which review you read. http://www.digitalversus.com/digital-camera/fujifilm-finepix-s1-p18466/test.html for example, was not too impressed. Hence I was interested to see if anyone had actually tried one. Maybe the problem is...

    Fujifilm Finepix S1

    I was looking in a local branch of Jessops and thought that this camera might be a contender for use in bird photography. It looked a bit more compact than the HS50, but any thoughts on their relative merits? I can't find much on here. I've briefly tried digiscoping, but was looking for...

    Classic books on North American birds

    "Wild America" by Roger Peterson and James Fisher might fit your requirements. It's widely regarded as a classic. In 1953 Roger Tory Peterson took English ornithologist on a 25,000 mile tour of some of the wildest parts of America from Newfoundland down to Mexico and back up to Alaska and this...

    wex photography

    They seemingly used to be known as Warehouse Express, which I think had a reasonable reputation. Their website shows a showroom in Norwich, so it's not just an anonymous postal address.

    Thinking of buying a bridge camera

    Surely there must be some trade off between increasing magnification power and focusing / response time? Also zoom lenses in telescopes seem to work better with a more limited range (hence the Swaro 25-50x) so I presume that the same will be true for cameras. One other thing that I would look...

    Home made Adapter for Samsung Galaxy S2

    I'd like to make something similar to connect a Nokia Lumia to a Swaro eyepiece. How did you make the ring? Did you mould it somehow from cast flexible epoxy?

    Winged eyecups

    Any thoughts on what would work best on Zeiss Victory 8x32 I waguely recall from many years back there being some mention of winged eyecups making misting of the eyepieces more likely due to reduced air flow. Any truth in this? I've always wondered why they are not fitted as standard if they are...

    Winged eyecups

    Has anyone tried winged eyecups? I think that there are a few available such as one in the Avian range. the idea is to keep out ambient light, which can be a problem in certain conditions, especially when the direction of the sun is such that light is relected off the eyepiece glass. I recall...

    Blurred Falcon from Spain

    I'm pretty hopeless on raptors, but on such a blurred photo can you eliminate female or juv red footed falcon? It would be pretty common in Spain, I'd guess
