@grrlscientist great article about recent #research on the #eggmimicry in #cuckoos with fascination information about the number of distinct #eggvariations a cuckoo female can produce to be able to mimic as #broodparasite a greater diversity of #hostspecies. Fascinating are especially the findings about the genetic basics for all that in the European cuckoo.

Cuckoo eggs match the eggs of their adoptive hosts thanks to (mostly) loci inherited from their mothers, who put them there — impressive multifaceted genomic study https://buff.ly/r8xpxaR

Here's a neat observation on #iNaturalistNZ. iNat user "catchwords" took an excellent set of photos of a shining cuckoo, pīpīwharauroa, in the Coromandel, NZ, eating caterpillars of magpie moths, mōkarakara.
No other bird in NZ eats these caterpillars, as the caterpillars sequester the poisons from the groundsel plants they eat, similar to what monarchs do with milkweeds. The stiff hairs on the caterpillars are also known to pierce the lining of bird gizzards.
Shining cuckoos typically squeeze out the innards of the caterpillars and eat those and then discard the skin.
The birds can also eat cinnabar moth caterpillars in NZ, which were introduced as a biocontrol agent for ragwort. Like magpie moths, cinnabar moths sequester the toxic alkaloids in the ragwort they feed on. Shining cuckoos don't care.
Many birds in the family Cuculidae, the true cuckoos and koels, are known to eat hairy and toxic caterpillars that other birds avoid.

Bid to save early #rewilding site that hosts rare #nightingales and #TurtleDoves
#Conservationists have launched a £1.5 million appeal to buy #farmland that was left to #nature 37 years ago
by Emily Beament
Tuesday 18 June 2024"A farm left to nature years before 'rewilding' rose to prominence has become a unique and important site for wildlife, say conservationists launching a bid to save it.
"The owner of Strawberry Hill, near Bedford, stopped farming his land 37 years ago, with once-arable fields reverting to #scrubland that is now a haven for a host of #wildlife including threatened nightingales, #cuckoos and turtle doves.
"But the 150-hectare (377-acre) site has no official designations or protections, and following the owner’s death, there were fears the land could be sold and returned to agriculture.
"After gaining a temporary stay of execution for the site, the #WildlifeTrust for Beds, Cambs and Northants (#BCN) has raised enough money to buy half the land.
"Now the conservation charity is launching a £1.5 million appeal to secure the whole site, saving the habitat and its rich wildlife and providing a 'unique' opportunity to have a decades-long head start on rewilding the land for nature."

#Cuckoos evolve to look like their hosts—and form #NewSpecies in the process https://phys.org/news/2024-05-cuckoos-evolve-hosts-species.html
#Coevolution with hosts underpins #speciation in brood-parasitic cuckoos https://www.science.org/doi/10.1126/science.adj3210
"Each species of bronze-cuckoo closely matches the appearance of their host's chicks, fooling the host parents into accepting the #cuckoo. The study shows how these interactions can cause new species to arise when a cuckoo species exploits several different hosts."

Dear Cuckoos,
I'm talking about those cuckoos who like to espouse extreme position, and oftentimes also like to tell other how to live their lives. I've not tossed away the shackles of heteronormativity, mononormativity, and neuronormativity, only to start entertaining other dogmas.
If I see too much dogma spewed at me, it hurts my mental health. Self-care in this case means muting you, or blocking you.
Sincerely,
Your Autistic Life

AAAS: "Two of these eggs are impostors. Can you spot them?" A classic mimic is the African cuckoo (Cuculus gularis), which can camouflage their eggs to match the eggs of the unwitting mothers who will end up having to raise the miscreant hatchlings. "But the fork-tailed drongo (Dicrurus adsimilis)—a glossy, red-eyed bird native to southern Africa—isn’t so easily fooled." In a study just pulished in the Proceedings of the Royal Academy B, 'drongo moms can spot the counterfeits with 94% accuracy, despite cuckoo eggs being an almost perfect visual match for their own.' The drongo apparently homes in on subtle variations in color + speckles patterning on the surface of their own eggs + spot the counterfeits. "Each female has a unique egg type, helping her spot impostors with accuracy that outstrips both humans and computer models." In the two drongo clutches in the photograph, the cuckoos failed to accurately replicate the speckled appearance of the other 2 eggs. I guessed wrong. See if you can do better. #parasite #cuckoos #ornithology
In both cases the parasitic egg lies at 4 o'clock. Congratulations if you got it right.

Egg signatures allow #drongos to identify #cuckoo forgeries almost every time
https://phys.org/news/2023-07-egg-signatures-drongos-cuckoo-forgeries.htmlWhen perfection isn't enough: host egg signatures are an effective defence against high-fidelity African cuckoo #mimicry. By Jess Lund et al. https://royalsocietypublishing.org/doi/10.1098/rspb.2023.1125
"African #cuckoos may have met their match with the fork-tailed #drongo, which can detect and reject cuckoo #eggs from their nest on almost every occasion, despite them on average looking almost identical to drongo eggs."

For a group that loves calling people they don't like "cucks"; the American right is not saying very much at all about #ClarenceThomas and his relationship with #HarlanCrow

@petewalkden I said to a hotel receptionist on #Mull that it was lovely to hear #cuckoos as we no longer hear them at home. She said that being woken by one in the early hours gave her a slightly jaundiced view of them. Actually disturbed one on a walk and “she (should be he) singeth as she flies” is quite correct.

Saw some bird photographers gathered at a spot at Lorong Halus, Singapore, then spotted what they were shooting: a Chestnut-winged Cuckoo (Clamator coromandus). Spotted on 6 Feb 2019. Listed as an uncommon migrant in Singapore.
