    Wryneck leaning to his side

    It's well known for his weird attitudes when caught, or near the nest, but this one was just leaning to the left, for a minute or so. It could be mimicry, trying to look like a piece of wood, as we can hear alarm calls ... ? https://www.youtube.com/watch?v=NE2dJcDs3m0

    Bullfinch - Does it also sing in a frequence we cannot hear?

    Apparently some birds really produce sounds above their hearing range, here is a recent study : http://www.cell.com/current-biology/fulltext/S0960-9822(18)30074-5 "Black Jacobin hummingbirds vocalize above the known hearing range of birds" : Christopher R. Olson,, Marcela Fernandez-Peters...

    Lone chough - window banging since September

    Sounds like some Hitchcockian - or Jungian - effect ! Are you afraid of the archetypes constellation ? Just kidding, of course... Maybe try to record it on video, if you can ?

    Bullfinch - Does it also sing in a frequence we cannot hear?

    I did some *internet* research about that not so long ago, and I was surprised to learn that birds can not hear ultrasounds/high frequencies. This doesn't mean they can't produce these sounds of course, but it wouldn't make much sense ? Their hearing capacity and range vary a lot with species...

    Common vs agile frog

    New one, much bigger, same location It was on the bottom, caught when I wanted to remove some organic matter with a net. Jumped back in the water before I manage to have a look under the feet....

    Common vs agile frog

    Thanks, that's what I was told, invasive species Pelophylax most likely P. ridibundus (although I see some call it Rana ridibunda... Is there any recommendation about what to do with it ? It's a private pond, but I'm vegetarian... I asked local specialists, they didn't answer that question...

    Common vs agile frog

    Thanks... Ok.... I need to buy a net and try to catch it.

    Common vs agile frog

    This young frog was found in western Switzerland where both species are present, body is maybe 4 centimeters long, I suppose it's born in 2017 ? Is there a way to know which one it is ?

    A new parrot taxon from the Yucatán Peninsula, Mexico

    "As a consequence of carried out analyses, we proposed the taxonomic position of the new Amazona. The significant differences in morphometry, morphology, behavior and vocal features imply that the new parrot deserves species status under the typological, morphological, phenetic, as well as...

    Wryneck feeding like a woodpecker

    I understand both of them were present in England/UK... I don't know why they became so rare. Reading local reports, it seems Wrynecks respond very well to the number of nesting boxes. Apparently they prefer wood-concrete nest boxes, and they like to have a choice, several boxes not too far...

    Wryneck feeding like a woodpecker

    Thanks Ken ! (for info you have to click on thumbnails under the photo I linked to see better shots), their population is apparently growing recently in my area, I had seen or heard some of them since many years, but couldn't come as close as these ones. Maybe that species will also rise in...

    Wryneck feeding like a woodpecker

    another observation... I found 2 birdhouses near the Wryneck's nest with... one egg inside ! The nest itself had 9 eggs. The first box is maybe 30 meters from the nest - also in a birdhouse - the other maybe 200 m. Another intriguing detail, both of these nesting boxes with one single egg have...

    Wryneck feeding like a woodpecker

    I know that they belong to the same family, but I had read a few time that they seldom feed against trunks like most woodpeckers do. So in case this could be of some interest for someone - despite the backlight - this Wryneck spent a few minutes against an old apple tree ...

    New raptor vs drone video - eagles capture drone

    Golden eagles capture drone in Austria : https://www.youtube.com/watch?v=FX3uOQiZs0A Funny to see their behaviour, as if it was a prey. (we see more and more videos of drone vs birds, I fear the props although very light, could be dangerous, did anyone try to put his finger when they are...

    New light on peacock display

    Makes me think of this little girl in blue... her dress was apparently too provocative for this peacock, who tried to attack her. Luckily she ran faster than him.

    Global warming figures are becoming even worse (Earth Times)

    I'm very skeptic about the agenda behind all this, how can you pretend to harness CO2 emissions, while the world population is doubling every 40-50 years ? The same people who whine about green house gas, are pushing for more growth, more developpment, more immigration, more everything ...

    distance between black cap chickadee houses

    I heard about 50 meters, but that's for great/blue tits in Europe. It's the same kind of bird, but I have no idea if the distance is similar for this American species.

    White-headed Stilt ? central Thailand

    Thanks again. I mentioned taxonomy because I was wondering if this could be some form of hybridization between both species/subspecies, and in your ebon website link, C. Perez is asking the same question: As both forms are expanding, and both forms would be now breeding in north Sumatra (First...

    White-headed Stilt ? central Thailand

    Also if they are Black-winged, they may be related, as both birds have the same unusual neck pattern, if not colour. To make things more complex, I see that White-headed is/was sometimes described as a subspecies of Black-winged.

    White-headed Stilt ? central Thailand

    Thanks for these examples Great info, I had never seen this black neck patch here in Europe nor in Thailand, it's a bit tricky ! So White-headed Stilt with more extensive black patch, thicker around the neck sides, and maybe the white space between the neck patch and the black upper-mantle a...

    White-headed Stilt ? central Thailand

    Thanks. That was my idea too. Also the brownish bird may be a young female ? I had some doubts after looking at Thailand's birdlists, and even the very few range maps I can find on the web for this species. My Robson's book mentions sightings in Cochinchina, which is today's Cambodia and south...

    White-headed Stilt ? central Thailand

    Hello, looking at my Robson's Birds of SE Asia, this couple look like White-headed Stilts, but would this be out of range in Bueng Boraphet ? If Black-winged, any key to id ?
