ANTARTIC PENGUINS CHAMPIONS OF POWER NAPS

Microsleep in humans are dangerous when driving, but just now, researchers found out penguins dominated microsleep, using these short sleep periods as strategy to balance sleep and vigilance requirements. An international team of researchers at the King George Island were looking at breeding chinstrap penguins (Pygoscelis antarcticus) using remote electroencephalogram monitoring, to they found out penguins nodded off more than 10,000 times a day, for only around 4 seconds at a time, but penguins still managed to accumulate close to 11 hours of sleep.

The brown skua (Stercorarius antarcticus), are very smart birds, and one of the main predators in nesting colonies. During incubation, skuas are known to prey on penguin eggs mainly on the border of the colony. As one penguin parent must therefore guard the eggs or small chicks continuously while its partner is away on foraging trips lasting several days, they face the challenge of needing to sleep while protecting their offspring In addition, they also have to effectively defend their nest site from intruding penguins, they need to stay alert.

-Recordings showing typical microsleep episodes in chinstrap penguins.

The investment in microsleeps by successfully breeding penguins suggests that the benefits of sleep can accrue incrementally.

Reference (Open Access): Libourel et al. 2023. Nesting chinstrap penguins accrue large quantities of sleep through seconds-long microsleeps. Science

Remember to read about the contestants before voting!

Brown Skua

Brown Skua prey upon penguin chicks, and live mostly in the Antarctic. They are pretty heavy birds, challenging some gulls as the heaviest shorebird. They are also known to identify individual humans, which means they’re actually quiet smart! They are also known to play with humans, and bond with ones that live in or around the Antarctic for a long period of time. Learn More!

European Dipper

The European dipper is Norway’s national bird. They are in fact not named for their diving, but are rather named for their habit of bobbing up and down as they stand in the middle of a stream. Their favorite food is aquatic invertebrate, but specifically they love aphipod shrimp. Learn More!

Access Denied: The Inaccessible Island Rail

The Inaccessible Island rail (Laterallus rogersi) is a rarely seen member of the rail family, Rallidae. Part of the reason for its obscurity is the place in which it resides: Inaccessible Island, part of the Tristan da Cunha archipelago in the southern Atlantic Ocean. These islands are extremely remote, and until 2019 it was unclear how L. rogersi even came to be there. We now know that the species colonized the island some 1.5 million years ago, originally coming in from South America and subsequently losing its ability to fly.

In addition to its unique evolutionary history, the Inaccessible Island rail's greatest claim is that it is the smallest flightless bird in the world. Individuals weigh between 35 to 49 g (1.2–1.7 oz) and can be 13 to 15.5 cm (5.1–6.1 in) long from beak to tail. Members of both sexes are dark brown with red eyes; some may have white striping along the underbelly or wings. Females tend to be slightly smaller and lighter in color than males.

The Inaccesible Island rail can be found on all habitats on the island in which it inhabits; these include low mountains and fern brush though the species is most abundant in the grasslands that grow close to the rocky shore. Within these habitats, L. rogersi is largely diurnal. They freely forage for invertebrates, including earthworms, beetles, and moths, as well as seeds and berries; as they have no natural predators they have few defenses against potential threats, although they can run extremely fast when alarmed.

Adults are highly territorial, and when two rivals of either sex encounter each other they will display by lowering their heads, circling each other, and calling loudly until one of them concedes. Males and females mate for life, and build nests in the tall grass. The breeding season is between October and January, in late summer, and females lay a clutch of 2 eggs. Both parents take turns incubating the eggs until they hatch. Chicks can be vulnerable to predation by the migratory brown skua, so parents guard the nest fiercely. The time it takes for chicks to fully mature is unknown, as is the average lifespan in the wild.

Conservation status: The Inaccessible Island rail is considered Vulnerable by the IUCN. The island's population is believed to stand at about 5,600 adult birds. While the island's ecology is currently stable, researchers believe the species would be seriously imperaled if invasive species such as house mice, feral cats and brown rats were introduced. Access to the island is currently restricted, and the island has been declared a nature reserve by the Tristan da Cunha Island Council.

Moons 4-5

MURKCLAN - a group of mercats living within the shadowy tangles of a kelp forest.  Known by the other clans for their dark pelts and secretive natures.

🌊 LEADER: Icebergstar - a large white tom with black paws and ears

🦑 DEPUTY: Urchinfleck - a dark grey she-cat with darker speckles and stripes; Apprentice: Belugapaw

🫧 MEDICINE CAT: Fretbelly - a blue tom who’s scales have darkened with age, he has a white underbelly

🌊  WARRIORS:

Foamtail - a dark yellow tom with large white stripes on his tail

Anemoneclaw - a spotted ginger she-cat with some white markings

Sunnyfreckle - a speckled yellow tom

Snailfang - a dark brown spotted she-cat

Sandstripe - a dark yellow tom with a brown dorsal stripe

Belugatide - a white tom with light brown paws and ears

🦑    APPRENTICES: [currently none]

🫧   QUEENS + KITS:

Skua - a light brown tabby she-cat with jagged stripes, formerly a loner

Conch - a pale ginger tabby tom-kit

Basalt - a dark grey she-kit with a dorsal stripe and golden eyes  

THE UPWELLING - An oceanic season marked by brisk winds, cold water, and plenty of sunlight.  This particular combination causes an explosion of life and activity in the sea, making for plentiful hunting.

MOON 4

🌊 Skua has fully healed from the strain of giving birth.  Icebergstar and Urchinfleck sit down with her to discuss what training they’d like her to go through.  The kits are being quite disruptive and naughty as their mother tries to have this important conversation.  Urchinfleck nips Basalt on the rump.

🦑 Icebergstar, Anemoneclaw and Belugatide chase a loner off of MurkClan territory.

🫧 Urchinfleck and Foamtail take Skua out hunting with them.  They discover a shark picking clean a carcass, its easy to see that there will be no leftovers here.  Foamtail can’t help but make comments about how much he hates sharks.

🌊 Sandstripe, Snailfang and Sunnyfreckle go hunting together.  Snailfang suggests that they go hunting closer to the rocky shore, it’s been a while since anybody has hunted there.  It’s an excellent suggestion and the group brings plenty of prey back home!

MOON 5

🌊 Icebergstar and his son, Belugatide talk to each other about how their lives have been going.  Icebergstar is proud of his son and how much he has grown and is continuing to grow.

🦑 Sandstripe feels that Skua hasn’t been taking her duties seriously and won’t be fit to become a fully fledged member of MurkClan.  Icebergstar learns about how Sandstripe feels and talks with his clanmate about why he feels this way.

🫧 Icebergstar puts together a training session for Sandstripe and Skua.  It goes just as he hoped it would!  Skua is able to show Sandstripe just how talented of a hunter she is already.  The two exchange tips as they practice different hunting techniques together.

What kind of bird is Azazel associated with?

Description

In the extra-canonical text the Apocalypse of Abraham (c.1st CE), Azazel appears as an unclean bird who came down upon the sacrifice which Abraham prepared. (This is in reference to Genesis 15:11: "Birds of prey came down on the carcasses, but Abram drove them away" [NIV]).

The Apocalypse of Abraham describes him as a carrion bird.

Possible Species

Birds of prey or predatory birds, colloquially known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion.

Birds of prey such as hawks, falcons, eagles, osprey, vultures, and owls are familiar carnivorous birds.

Birds that are regularly known as carrion-eaters include: vultures, buzzards, condors, caracaras, eagles, hawks, crows, ravens, and other large corvids, gulls, skuas, and terns

Specific

{Criteria: bird of prey that also eats carrion and is found in Israel}

Crows, jays, and magpies Order: Passeriformes Family: Corvidae

Brown-necked raven, Corvus ruficollis

Common raven, Corvus corax

Eurasian jackdaw, Corvus monedula

Fan-tailed raven, Corvus rhipidurus

Hooded crow, Corvus cornix

Rook, Corvus frugilegus

Hawks, eagles, and kites Order: Accipitriformes Family: Accipitridae

Black kite, Milvus migrans

Common buzzard, Buteo buteo

Eurasian sparrowhawk, Accipiter nisus

Greater spotted eagle, Clanga clanga

Imperial eagle, Aquila heliaca

Lesser spotted eagle, Clanga pomarina

Long-legged buzzard, Buteo rufinus

Steppe eagle, Aquila nipalensis

White-tailed eagle, Haliaeetus albicilla

Alrighty and HERE ARE OUR CONTENDERS!!!

Tag for the polls: #bird battle

DISCLAIMER - I wrote the round one blurbs when I was very sick and half awake, so if you see any mistakes PLEASE TELL ME! Nicely, obviously, but I want to make sure they sound good for round 2. Thank you!

I know there’s a lot of them, but man there’s SO MANY GOOD BIRDS! There were a few times where people didn’t put what specific subspecies for some birds, so sometimes I’d have to choose one. I tried to choose one that represents that bird the best!

I don’t know when the polls will begin, I’m doing some research on the birds so that people can read about them before they vote.

If one of your favs didn’t make it in, don’t worry they’re a winner in my and your heart.

If you are wondering where the Pigeon (Rock Dove) is, THEY ARE THE FINAL CHAMPION! At the end of this bracket, the winner will face off against the mightily popular Rock Dove! Will they be able to beat such a tough challenger? We will see…

Also, a note on how I set this bracket up: I put all the birds in a numbered list and then used a number generator. I think the matchups we got were really interesting.

Starting a little birdwatching journal :) I got a pocket bird ID handbook in town today and went to look at some shore birds!

I identified some great black backed gulls floating and feeding on the sea, a lesser black backed gull taking a nap on top of a lamp post, a couple of house martins flittering back and forth between rocks, a scraggly looking rook grooming on a lamp post and a large brown bird with a longish neck that I couldn't make the features of very well, but maybe a great or arctic skua?

Stood there for about 15 minutes trying to identify what I thought was a bird, and what I thought was a male hen harrier, but it was, in fact, a chimney pipe

As I was typing the above I saw a gull-like bird that was mostly black with a white head but I couldn't figure out what it was :( However I did also see two black headed gulls out of breeding season ambling on a pond near the coast and more scraggly looking rooks on a low beach hut roof!

I also spent like 15 minutes standing by a bush on the side of the sidewalk trying to ID a tiny bird with a really distinct "tweep" call, an unpatterned brown back and black wing tips. Gonna try to look it up later, my book didn't have anything that matched.

And now I have wandered to the other side of town and I am So hungry so I am going to conclude my birdwatching here and go to lidl to get a pizzini and then try to find a bus home

Note to self: bring binoculars next time
