    Bird confuses police with mimicry

    When I worked in Harlow there was a Blackbird that convincly mimicked the sound of a forklift truck reversing.

    Green Listing 2024 - Joint Thread

    I had been expecting a Nightingale for the last few days, as they tend to be common along the canal I cycle along on the way to work, but I had to go to the prime spots nearby to find one.

    Rare(?) Orchid, Cyprus

    It is localised, but not rare. If you check this map, you can see its distribution is limited. No password should be needed (but the specific locations are hidden). https://observation.org/species/81348/maps/?start_date=2015-04-16&interval=86400&end_date=2024-04-10&map_type=grid25k

    Green Listing 2024 - Joint Thread

    I also saw Pied Flycatcher today (I had expected one yesterday: I actually passed the site where I found this bird!) Common Whitethroat (which usually shows up on 14 April) was an expected early arrival on my patch based on sightings nearby yesterday (my earliest ever in NL (11/4), BE (10/4), UK...

    After failing to find Ring Ouzel at what tends to be the best location nearby (the highest accessible slag heap) I went to one nearby that has only recently become accessible. Although this heap is far less impressive, here I found 21, my third best day ever (the other two were on the Dutch...

    First Butterflies 2024

    Very warm today, so no surprise that I saw my first Orange Tip, Green-veined White, Small White and Comma (as well as the first local Holly Blue).

    I have been failing to find anything but Swallows thusfar, which are also still patchy. Over 25 °C tomorrow...

    The ultimate range maps

    That's indeed nice, although I wish we could get rid of Mercator once and for all. Gall-Peters would be better as most species diversity is in the tropics.

    Phylogeny of birds

    Me too, but luckily there's excel to count for me: Agostinho Antunes, Edward L. Braun, Erich D. Jarvis, Guangji Chen, Guojie Zhang, Iker Rivas-González, Josefin Stiller, Mikkel H. Schierup, Qi Fang, Shaohong Feng, Siavash Mirarab, Uyen Mai.

    It's Allium neapolitanum.

    Green Listing 2024 - Joint Thread

    After a very stubborn rain front finally moved east, I thought some vismig might follow and I was right: a good afternoon/evening for Marsh Harrier and Osprey, with a Tree Pipit flying across as I was leaving.

    Petition for a dedicated sub-sub forum for eponymous name rants

    In some cases (like IOC updates) it is unavoidable that disappearing eponyms will show up and some factual background info will be added. About 800 such cases to go then... ;) I'd like to see any deviation into ranting deleted.

    My first Holly Blue of the year in Utrecht, the Netherlands.

    Plant ID please? White flower, six petals, rural roadside verge, possibly immature - Norfolk in March

    Drooping Star-of-Bethlehem, Onithogalum nutans. Intrigued why you'd call a flower "immature". Just because it is greenish?

    A (heard-only) Yellow Wagtail today (which will go into my list as Blue-headed as its the most likely option by far). I then went to the closest population of Black-tailed Godwits and saw four, which is a good score. A few Curlews as well, but no surprises at all. It was windier than expected...

    Latest IOC Diary Updates

    I prefer the chosen solution: it mentions an actual distinguishing feature in this very homogeneous genus! However, the eponymic name has been used in field guides much longer. In Beehler's Birds of New Guinea from 1986, it is called Mackinlay's Cuckoo-Dove. Only Coates & Peckover (2001) mention...

    An also rather unsurprising but nonetheless welcome Blackcap on my way to work. The corner where I tend to see the first one in town is currently "off-route" because of road works, which may have prevented an earlier date.

    A Green Sandpiper this evening was probably the least surprising addition I could have had!

    Balearica

    Yes, they were thought to occur in the Balearic islands. Brisson wrote in 1760 "On le trouve en Afrique et dans les Isles Baléares." This was based on older work, e.g. by Aldrovandi (1599): Ulisse Aldrovandi – Crowned Heron Bird: Ein handkolorierter Stich von Aldrovandi aus dem 16. und 17...

    Accipitridae

    It should be Melieracini linguistically. I cannot comment if the change is allowed.
