    Could migration routes be traced back to where birds evolved in ancient times?

    Hey DMW - how you doing!? I´m a bit confused with what you are on about tbh.... Of course natural selection is a mechanism and cause of evolution...adaptations (in this context) are often behavioural traits that make an organism better suited to its environment/s....i.e. migratory change which...

    Could migration routes be traced back to where birds evolved in ancient times?

    This is more the ethology of migratory behaviours and evolutionary selections, so it isn´t suggesting that at all. Migratory birds are driven by instinct (photo-period change) as well as choices, food weather etc In the case of Yellow-browed Warblers it is a good example of adaptive migration...

    New AX Visio 10x32 binocular

    AI tech is clearly a developing system and will only get better. It´s application for remote sensing development is exciting to me. Personally I´m not a great fan of this Swaro development simply because it detracts from the connection to nature and understanding. I do however understand that...

    New camera and new settings

    Hola chicos! I wondered if anyone could help me with some questions regarding good settings for the OM1 with M.Zuiko 150 -400 For instance what Auto focus mode to select and if it is a good idea to have release priority on or off...off seems to be the conventional wisdom but I have read...

    Could migration routes be traced back to where birds evolved in ancient times?

    Vagrancy in Birds by Lees & Gilroy published by Helm recently is a great read! Interestingly this hypothesises on the vagrancy of Yellow-browed Warbler being migratory pioneers - Ringing recovery of Yellow-browed Warbler in Andalucia confirms over-wintering in consecutive winters. First...

    Could migration routes be traced back to where birds evolved in ancient times?

    Hi David - Sure that would be true for shorter range migrants (although they are still triggered by daylight length) and of course as I say is still a factor but longer distance migrants (note I refer to long distance migrants in my post above) are more impacted by climate change issues as they...

    Vagrant African Vultures to Europe

    As African Vulture population plummet the increased effect of the Eurasian Griffon Vulture youth dispersal conveyor belt has the potential of bringing more of these declining Vulture species to Europe. As part of the ongoing conservation diagnosis management required we are continuing to...

    Could migration routes be traced back to where birds evolved in ancient times?

    It is interesting thought for some species. European Turtle Dove is perhaps a good example - most of the Sahara at one point would have looked much like their wintering grounds in the Sahel and there are of course resident populations of S. t. arenicola in NW.Africa . It is probably reasonable...

    Victory FL vs SF

    I know right! - Does seem to me perhaps as the drive for optical brilliance increases and the resulting associated costs increase then perhaps some external build elements are somehow relegated to second importance or cheaper components? ....who knows, I'm sure they would admit to it :unsure...

    Victory FL vs SF

    The Conquest are probably housed in some of the best tough and well constructed housing of all three but the FL's are really good. I owned the 8x32 FL's for a long while before upgrading to the SF's 8x42 no problems with the FL's at all - optically they feel really different in my view with...

    'RetroPorro' a Possibility says Leica

    I've often thought - It would be great if they brought back the old build Trinovid (BA/BN) - I know it is a roof prism but... Fantastic hardcore build, well balanced, probably the best eye cups in the business (IMO) and could actually stand-up to hardcore use (unlike most of the newer...

    Unsustainable Turtle Dove and Common Quail shooting holidays in Spain

    Hi Birforum-ers This really has me rather angry ! https://www.bookyourhunt.com/en/dove-hunting-in-europe I am particularly concerned about the promotion of both Common Quail and Turtle Dove shoot holidays which run completely contrary to these aspects they state on their website: "We believe...

    Help - Slow ferry to Morocco?

    I never use the fast ferry - terrible Dolphin and Whale killer! Transmed from Algeciras takes about 1.5hrs, normally see quite a bit from the route to Tangier Med as there is often seabirds and cetaceans, sometimes raptors too!

    ATX95 vs 85

    For me the 95X is the best but the weight etc is a real drag in the field, it is just really cumbersome too! I currently have the 85mm for a couple of reasons, my main watching is raptor watching and the increased fOV at 25x is a bonus also the 85 is just a very neat compact (more so than its...

    Troubador's Mini Review: Black vs Grey SF

    To be fair the armour is not of the quality of the black version from what I've seen - they sold a premium binocular with **** armour so perhaps they should rectify the situation? Great bins apart from that mind!
