The egg of the majestic and very, very large Emu (Dromaius novaehollandiae), is also quite majestic, and very, very large. Emus will lay several clutches of five to fifteen eggs during the breeding season, and which can add up in weight quickly. Each egg weighs around 450 to 650 grams, or about 1-1.5 pounds! It’s a good thing that Emus are ground nesters; I can’t imagine trying to keep all of these up in a tree.

Emu eggs start out a light green, and grow to a dark green during incubation. This egg here, which is obviously a little bit past its incubation period, has turned nearly black with time.

oh honey believe me i have so many thoughts about this dumb family so here’s some random ass poindexter kid headcanons (you can find my original post outlining them generally here)

  • the best at piggybacks
  • lucas knows the binomial name for, like, everything
  • “emu” “Dromaius novaehollandiae, at least make it hard”
  • he’s the only brunette in the family and florence always jokes that he’s adopted
  • doodles all over his notebooks
  • people keep asking him on dates and he just gives them a Look
  • why would he want to date when he has science
  • matilda has freckles. goddamn. everywhere
  • she’s so freckly it’s mental
  • speaks basically fluent french so she and nursey have Secret Bitch Sessions whilst dex glares at them

  • has two girlfriends and two boyfriends and made a rota for skating partners so nobody has to “fight over him”
  • matilda and catherine take turns painting his nails different colours
  • he’s really into biology and likes to listen to lucas explain his notes

These adorable Emu (Dromaius novaehollandiae) chicks have been a part of the Horniman’s collections since 1910! We love the way the larger chick peers downwards and expression on his or her face! This face was particularly striking as we had to use a lifting device to get him/her up to a high shelf in the next taxidermy store room!

The smaller chick is posed in a more upright stance and they were likely once displayed together as a family group. Emu chicks hatch from beautiful blackish green eggs. The eggs are incubated by a dutiful dad who forgoes food and drink while sitting on the eggs. The chicks' broken lines and speckled feather pattern help break up their outline, helping them avoid detection by would-be predators. These Australian birds may start off quite small, but adult Emus are the second tallest bird species in the world with fully grown adults standing just under 2m tall.

November 19, 2016 - Red-billed Gull or Mackerel Gull (Chroicocephalus scopulinus or Larus novaehollandiae)

Sometimes considered a subspecies of the Silver Gull, these birds are found in New Zealand and surrounding islands. They eat a variety of aquatic and terrestrial animals, including squid, jellyfish and anemones, insects, crustaceans, arachnids, small fish, frogs, and birds. One of the smallest and most common gulls in New Zealand, they are often seen in coastal towns scavenging on trash. Breeding pairs are monogamous and form long-lasting bonds. On the mainland, breeding takes place in large colonies, but on smaller islands breeding pairs nest alone or in small groups, probably to avoid predation. Males and females spend about equal time nest building, incubating eggs, and caring for the chicks.

January 30, 2016 - Superb Lyrebird (Menura novaehollandiae)

Requested by: askthethoughtful

These lyrebirds are found in leafy forests along the southeast coast of Australia. Their diet consists of invertebrates, such as spiders, worms, and insects, along with seeds. To attract mates, males display with their tails over their heads while singing, mimicking sounds from the local environment. They are capable of perfectly mimicking a wide variety of noises, including chainsaws, cameras, and barking dogs. Females build the nests, incubate the eggs, and feed the chicks.

December 31, 2015 - Silver Gull (Chroicocephalus novaehollandiae)

The most common gull in Australia, these birds are found throughout Australia, New Zealand, and New Caledonia. Like most gulls, they are opportunistic scavengers with a highly varied diet including fish, invertebrates, seeds, berries, bird eggs, and human refuse. A highly gregarious species, they often congregate in flocks of hundreds or thousands of birds. They breed on small islands, generally in large colonies of up to 3,000 breeding pairs. Nesting in scrapes lined with plant materials, both parents incubate the eggs and care for the chicks.

The Tasmanian emu (Dromaius novaehollandiae diemenensis) went extinct in the late 1800′s as a result of overhunting and habitat destruction. This subspecies of the emu became isolated on the island of Tasmania during the late Pleistocene.

Two preserved skins were once held by the British Museum, but they have unfortunately been lost. The only other surviving remains are subfossil bones.
