Of the four new year birds for him the best was one of several Nelson’s Sparrows at Big Egg Marsh, always a great bird to see, and Corey saw several very well as the high tide forced them out of the marsh. The post Best Bird of the Weekend (Third of October 2020) appeared first on 10,000 Birds. How about you?
Our first Pied Oystercatcher eggs for this year’s breeding season were laid early and were due to hatch last weekend. This pair of Pied Oystercatchers never seems to have a problem with incubating their eggs. They take it in turns over the twenty eight days sitting or hovering over the eggs. Pied Oystercatcher egg.
There are still newly laid clutches of Pied Oystercatcher eggs on the northern section of Cable Beach , so there is hope still of more survivals. We are very pleased that at least one Pied Oystercatcher chick has survived this year when there has not been much good news for 2020. They do not attempt to breed for about seven years.
It didn’t occur to me till I started reading The Falcon Thief: A True Tale of Adventure, Treachery, and the Hunt for the Perfect Bird that there was also a possible threat to the eagle herself: poachers, who steal raptor eggs and chicks. McWilliam realizes he’s dealing someone special, a career falcon egg-thief.
I’m not sure what they think of 2020’s low water levels, but they looked happy! Perhaps the lake’s insects function like the Atlantic Horseshoe Crab eggs that shorebirds gorge on along Chesapeake Bay during their northward spring migration? That’s a lot of Northern Shovelers. Northern Pintail , female).
Following on from the sad loss of our first Pied Oystercatcher chick of 2020 the other eggs are now also hatching. Somehow the twenty eight days passed without the eggs being run over. Pied Oystercatchers always try and move away from the nest site as soon as possible once both eggs are hatched. Pied Oystercatcher family.
It does seem like the order is concurrent with the 61st Supplement, which came out in 2020, but Northwestern Crow is included as a full species. Plate 28 from Audubon Bird Guide, Eastern Land Birds, by Richard H. Pough “with illustrations in color of every species” by Don Eckelberry, Doubleday, 1946.
The Atlas was published in 2020, so these numbers may have been grown since then. A pair did lay infertile eggs in Iceland in 2018, but that’s about the only record I can find). It goes on to say that the Dutch population is estimated at 16,000-22,00 pairs. This Barnacle goose is part of a resident breeding flock in North Norfolk.
Penguins are shown individually in groups, in dense colonies, within habitat (ice, rainforest, beach), swimming in the ocean, and doing things–nose to nose with an albatross, feeding a child, placing an egg on its foot, sliding down ice. Netherlands: Oliver Plantema, 2020. by Otto Plantema.
In spite of our proximity, it spent a good while positioned as if it had eggs there. That number was a bit better than my first-day total from 2019, though a bit worse than 2020’s total. In spite of being a winter migrant, which only reproduces in the U.S. Was it practicing?
The “Owls and Albatrosses” chapter, for example, begins with Doug’s personal experiences observing of the nesting strategies of Malleefowl and a Moluccan Megapode, Australasian “chickens who lay their eggs in unusual ways and do not parent. And then we go back to the evolution of clutch size.
As we know from the French documentary La Marche de l’Empereur ( March of the Penguins) , the females skedaddle from the breeding colony once she produces an egg, leaving the egg to be incubated by the males, who fast for 120 days while keeping the egg in a flap of their feet. (I
Species Accounts are organized by family according to the 61st Supplement (2020) of the AOS Checklist of North and Middle American Birds (the 62nd Supplement came out while the book was in production, which is to be expected). Harrison, and Nests, Eggs, and Nestlings of North American Birds, 2nd ed. Baicich and Colin J.
I’m thinking here of books like Wenfei Tong’s Understanding Bird Behavior (PUP, 2020) and John Kricher’s superlative Peterson Guide to Bird Behavior (HMH, 2020).
318 – Burrowing Owl , 16 May 2019: An unbelievable find and a thrilling chase, this bird at Big Egg Marsh was as as astonishing as it was unpredicted. 322 – Black Vulture , 13 March 2020: To finally find my tenth new bird since my last set of predictions was wonderful, especially as it happened from my balcony.
The first eggs are usually laid at the end of May or sometimes in the first week of June, but this can vary depending on the weather. Both sexes incubate, with the eggs taking an average of 19 or 20 days to hatch. The clutch is two, sometimes three, with incubation usually not starting until the clutch is complete.
His first surmise seems like a good one – that the feathers are meant to hide the eggs from other female swallows seeking to parasitize the nest, by disrupting the parasite’s timing (if eggs are present, the parasite would know that the nesting mother is ready to incubate – that is, incubate not only her own eggs, but the parasite’s, as well).
I visited Tengchong in late 2020 and wrote about it – but I also went there earlier, in 2017, and this post shows some photos I took during that trip, along with the usual comments that seem to be much more about ridiculing my fellow humans (especially ornithologists and the like) than providing useful information on birds.
If you look at this header photo and then the header photo of our first camping trip in 2020 you will notice it is somewhat similar. We moved in slowly and soon observed that there was a well camouflaged nest with one egg in it. Black-fronted Dotterel nest with one egg.
From Hiro, we learn how Northern Pygmy Owls are “rule breakers,” not incubating eggs till all are hatched and then raising owlets that mature at the same rate even though the eggs were laid asynchronously (as most owl eggs are). Jennifer Ackerman is one of my favorite bird authors.

This may have been partly a leftover from the Victorian fascination with egg collecting (the infamous passion known as oology), but probably more from people’s burgeoning interest in the nests and eggs found in their gardens and fields, gateway artifacts to a newer hobby called birdwatching. The Harrison guides are out of print.
