Incubation in the #Anthropocene
Or "The bird that mistook its eggs 🥚🥚 for a plastic container"
🙄 This is its story: ⬇️ Thread ⬇️
This Kentish #plover pair incubated a nest of two eggs 🥚🥚 for 22 days, until it was preyed upon by a fox 🦊. But the fox left a strange "egg" 🧐 inside the nest. The female has continued to incubate it for weeks. In #albuferadevalencia
At the beginning of May 2021 the Kentish plover female laid 2 eggs. 🧐 Can you spot them in this photo? Some pairs are able to camouflage them very effectively.
A few days later they incorporated a peculiar third "egg" 🥚, which seemed lost outside the nest: a plastic container of liquid nicotine of French origin that the sea deposited there (see previous photo) 🙄

Days later, the wind 🌬️🍃 buried the plastic container with sand. The nest had two eggs again for a week, which were incubated normally.
On its 22nd incubation day the nest was predated by a fox 🦊. But the wind had once again modified the scene, this time removing the sand and bringing out this peculiar ... "egg" 🥚 again.
So this Kentish plover female decided to continue incubating her last "egg", adding nest materials in order to camouflage and thermoregulate the egg (protecting it from excessive insolation), rotating it and defending it with its characteristic distraction displays.
The male has not collaborated in incubation and has created courtship nest scrapes around the current nest, perhaps to convince her of her mistake and to start a new clutch. One of these nest scrapes is only 5 cm from where she incubates the plastic recipient (see green arrow):
This footage shows the Kentish plover male crouching over this same courtship scrape, to show it to the female, a common courtship behavior in the species. Without much success apparently
👀 So this Kentish plover female has been incubating a French plastic container of liquid nicotine for a month, convinced that one day the only egg that survived the predation of its nest will hatch 🐣.

La desinformación forestal como herramienta incendiaria ⬇️🧵hilo⬇️
Guía rápida para reconocer el fraude argumental de los 🔥🔥 🌲🌲 #IncendiosForestales impulsados por una mala gestión forestal, o de cómo lidiar con el cuñadismo piro-forestal en tiempos de #crisisclimática 1/n
Durante y tras cada gran #incendioForestal aflora la desinformación y la demagogia acerca de la situación de los "montes", a menudo con tinte de oposición política, un caldo de cultivo para iluminados abonados a la idea del “se veía venir”.
Un mantra que se repite a lo largo y ancho de los medios de comunicación de este país, como si la solución al problema de los #IncendiosForestales ya estuviera escrita con antelación, pero nadie se hubiera leído el manual.

😵 La incubación de los huevos 🐣 en el #Antropoceno
O el ave que confundió un bote de plástico con sus huevos y lo incubó durante 1 mes.
Esta es su historia: ⬇️Hilo. Ver 🎥al final⬇️
Esta pareja de chorlitejos patinegros incubó un nido de dos huevos durante 22 días, hasta que fue depredado por un zorro 🦊. Pero el zorro se dejó en el nido un extraño "huevo", que la hembra ha seguido incubando durante semanas. Su historia ⬇️:
@avesplayeras #ornitologia
A principios de mayo de 2021 realizó una puesta de 2 huevos. 🧐¿Puedes localizarlos en esta foto? Algunas parejas son capaces de camuflarlos de forma muy efectiva.
