A couple of weeks ago I introduced you to the pair of Pied Oystercatchers that were the first to start breeding along our coast this year. Sadly they were not successful with their first clutch of eggs, but are busily making nest scrapes again. We are hopeful that soon they will have laid another clutch of eggs.
The Cuckoo Cuculus canorus has a bad reputation because of its habit of laying its eggs on the nests of other birds, who then raise their young. The White-rumped Swift Apus caffer , a tropical African breeding species, was only discovered breeding in Europe in the 1960s. Curiously, they also breed in Iberia today.
We really don’t like the presence of Black Kites along the beach when the Pied Oystercatchers are breeding. The adult Pied Oystercatcher that is sitting on the eggs will lay as flat as possible to protect the eggs. Of course Black Kites also breed and at the moment there is a nest very close to the highway.
This year we have continued to monitor the breeding of several pairs of Pied Oystercatchers along the coast in Broome from Gantheaume Point to Willie Creek on the south side. The first eggs were laid in the first week of July, which is the case each year. Pied Oystercatcher sitting on eggs in the nudist area of Cable Beach.
Egg loss to predation has been extraordinarily bad this year and all of the nests mentioned in the last post were lost and all of the pairs of Pied Oystercatchers laid a new clutch of eggs. In fact they have not just laid once again, but many pairs have laid up to five clutches of eggs this season.
But no, my story today is about the birds that come in to breed on the heather moorland which dominates the high ground. It’s quite amazing how birds that we are used to seeing much of the year on coastal mudflats, exploiting the intertidal, change their habits and take to the hills to raise their young. And with good reason.
It’s a bang-up breeding year for super-endangered birds! The species, which migrates from the Russian Arctic to Southeast Asia, is down to about 200 breeding pairs in the wild, due to habitat loss and poaching. For the past several years, getting the birds to breed has been an exercise in futility. Both photos by the WWT).
There are thousands of shorebirds that visit Broome each year and the majority of them are now in the northern hemisphere hopefully sitting on eggs. Not all of our shorebird species migrate and those that reside here are also currently sitting on eggs, or thinking about laying eggs in the upcoming weeks.
This year is the eighteenth year since we discovered our first Pied Oystercatcher nest on Cable Beach in Broome and it didn’t take us long to realise that they are not at all successful at raising young due to egg and chick predation. He last raised a chick successfully in 2016 and has nested in this area since 2008.
Of the sixteen pairs of Pied Oystercatchers between Gantheaume Point and Willie Creek on the south side, which is a length of breeding territories covering 23 kilometres-just over 14 miles-only one chick fledges most years. There is egg predation, chick loss and sometimes possibly just some “bad parenting”!
Once again Pied Oystercatcher breeding season is fast approaching in Broome and we can expect the first batch of eggs to be laid within the next few weeks. We have also discovered that they are very rarely successful with the first eggs laid due to predation of either the eggs or the chicks. Flock of Pied Oystercatchers.
Male Phalaropes, Jacanas, Tinamous, and Rheas build nests, incubate the eggs and take care of the chicks. During the breeding season, adult males split from the flocks they normally live in and begin to advertise their availability to females by calling and performing body contortions. Some of the eggs will be lost to the elements.
Traditionally since 2000 we have encountered our first Pied Oystercatcher eggs in the first week of July, but this year one pair have decided to start laying eggs early! Sadly they have already lost one clutch of eggs to predation, so by July 1st this year they are on their second clutch. Pied Oystercatcher nest.
Ka’ena Point is also a breeding ground for the Federally protected Laysan albatross, where 45 nests were being carefully monitored by the non-profit Pacific Rim Conservation. The oldest Laysan albatross was last seen raising a chick on Midway Atoll in 2016, at age 66. They are docile and devoted parents who will not leave their nests.
Over the past few months there have been a lot of birds breeding around Broome with the excellent rain events that we have been having and the vegetation is at long last revived. Masked Lapwings have been busy breeding for some months now and some may well be on their second clutch of eggs. Masked Lapwing protecting a nest.
According to the McMurray hatchery , the “Silver Pheasant is considered a good ‘starter’ breed for people who want to learn more about raising pheasants” Hm. In one group, they added a blue egg to their nests. In the other, they added both such an egg and a peanut half-shell. What a weird world.
Since discovering our first Pied Oystercatcher nest on Cable Beach in July 2000 we have observed the breeding of these local shorebirds along the coast between Gantheaume Point in the south and Willie Creek in the north, which is a distance of 23 kilometres.
A few families have a small number of eggs in the clutches, like gulls or cormorants. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. The investment placed in each clutch bur seabirds is so great that only one breeding attempt can be seen to completion each year. So why do it?
They are usually seen singly or in pairs, but they sometimes form loose alliances whilst breeding. In such cases, the spurned donor has been observed helping to raise the brood. So there may be duplicity in the Dunnock household, but even the female can’t be sure whose chick she is raising.
We are into the second attempt at breeding for this season in Broome for Pied Oystercatchers. The first eggs are laid during the first week of July each year and if these eggs fail to hatch or the chicks are lost they will lay further eggs within a few weeks. Nest site with 3 eggs-one white!
It has been a few years since I could share some good news about the Pied Oystercatchers breeding along the coast near Broome. Hopefully you won’t mind me writing a bit more this year about Pied Oystercatchers during the breeding season! The two eggs normally hatch at least a day apart and sometimes longer.
After a very good Wet Season with substantially more rain than normal over the first few months of 2017 the land was flooded and a huge variety of birds arrived in the Broome area to take advantage of the ideal conditions for breeding. Australian Painted Snipe nest with four eggs. Four eggs in the Australian Painted Snipe nest.
Okay, they weren’t as fascinating as the birds of prey eating their, or the frankly still weird drawings of nightjars carrying eggs and woodcocks carrying chicks, but still, hornbills were cool because they sealed their mates up in holes in trees and then fed them as they raised the chick. We can hope!
Wood Duck ( Aix sponsa ) Female Incubating Eggs in a Nest Box “Many species of cavity-nesting birds have declined because of habitat reduction. This is the female incubating eggs in the nest box… and a couple of weeks later… then, at the ripe old age of 17 days, what’s going on out here?
The HBW even mentions the importance of Ruoergai for this species: “Key sites for migrants include the Ruoergai Plateau (China), which is also an important breeding area” Common Mergansers also seem to use these wetlands as breeding area. Understated elegance is also something the White-browed Tit is rather good at.
But when raised, they seem to have a sort of weird cape. In other words, they never raise their own young. Instead, they lay their eggs in other species’ nests, and let those nest-making birds (often significantly smaller than the cowbirds) raise their young. So that is a negative mark on both their records.
After 28 days of sharing the duty of sitting on three eggs we finally had the arrival of our first Pied Oystercatcher chicks for 2012 on Friday August 3rd. It is unusual for three eggs to be laid here in Broome and many eggs do not even hatch due to predation each season.
Being a westerner — raised in California, and now living in western Mexico — I was perhaps most excited about the migratory birds that breed in eastern North America. And then there was a Green Heron , not only showing us its nest, but also an egg. Then, around 4:00 p.m., And yet, there it was. But what could I do?
The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. Some Thai researchers looked at the breeding ecology of the Buff-breasted Babbler and published their findings in the somewhat unsuitable-sounding journal “Agriculture and Natural Resources”.
All three species mentioned in this article breed on these islands, but the Piratic Flycatcher employs a truly piratic strategy: the breeding pair targets a recently built woven nest, often by a Yellow Oriole or Yellow-rumped Cacique but they have also been recorded targeting the nests of other flycatchers.
Kirtland’s Warbler is a classic niche species; they breed in only very specific conditions, which occur in only a very specific area. this species breeds. Fortunately, there were still a handful of immature birds alive at sea, and a few years later they were back on Toroshima breeding again.
One of our male Pied Oystercatchers has been marked with an engraved leg flag “A1” and was one of the first pairs to lay eggs this season. Sadly the two chicks did not survive very long at all and the pair of Pied Oystercatchers were soon getting ready to lay more eggs. “A1” Preparing another nest site.
Among birds the Egyptian Vulture uses rocks to crack Ostrich eggs, the New Caledonian Crow and Woodpecker Finch (one of several Darwin Finches of the Galapagos Islands), uses sticks to extract grubs from inside a branch. Egyptian Vultures raised is isolation used rocks to crack eggs presented to them. The behavior was inherent.
Each year 120,000 birds visit the island to breed from March through August in burrows that riddle the landscape. After mating, a single egg is laid and incubation duties are shared by both parents. Setting out at night to avoid being caught by the large gulls, they can cover the 10,000 km journey in just two weeks.
As a Northeast birder I am familiar with the alarming decrease in the number of Red Knots along Atlantic shores and have signed petitions and written e-mails calling for legislation and rules that will limit the overharvesting of the horseshoe crab, whose eggs Red Knots depend on. million in the late 1990’s. Should the gulls be controlled?
I couldn’t help thinking this–me, the anthropomorphism hater– as I watched a pair of Philippine Eagles tend their nest, raise a chick, and tear monkeys apart in Bird of Prey: The Story of the Rarest Eagle on Earth , a well-crafted, beautifully filmed documentary with a mission. The Philippine Eagle has a kind face.
I should have known that birding High Island meant I would be 20 minutes away from a place where hundreds of thousands of shorebirds and waterbirds rest, feed, breed, and generally have a good time. I love American Avocets and I rarely see them in such marvelous breeding plumage, so I was in heaven. Clapper Rail. Back to the Flats.
It is currently Pheasant Coucal breeding season. Despite the fact that they are part of the cuckoo family they do actually raise their own young. Pheasant Coucals can lay up to five eggs, but we don’t know how often this actually occurs. The parent bird watched and the highway is not very busy at this time of year.
"All animals deserve humane treatment, including animals raised for food.” Proposition 2 ends the practice of confining certain animals raised for food in crates and cages so small the animals can barely move. It applies to breeding pigs, egg laying hens and veal calves.
A lovely looking and distinctive sounding bird (so they say, I sadly have not seen one…yet), the Kirtland’s Warbler can only be found during its breeding season in Jack Pine forests 5 to 20 years old in the northern Lower Peninsula of Michigan.
Another animal dies at the Calgary Zoo and more questions are being raised about their practices. In April 2009, unseasonably cold weather froze two whopping crane eggs. They were a part of the zoo’s breeding program for the rare birds. I don't track zoos, but this seems like an unusually high number of casualties.
Baird’s Sparrow by Seagull Steve Julie’s was not a wild bird, well, at least not one that lived outdoors: My Best Bird of the Year, and the 22 preceding, was Charlie, a Chestnut-fronted Macaw I got as a captive-raised fledgling in 1989. She made a fool of me when I first met her, and again when she left me.
During the breeding season, some Cattle Egrets look like teenage girls who have just discovered the existence of make-up, and consequently massively overdo it. While having somebody else raise your chicks like an attractive strategy to me, it is not without dangers. It is probably all downhill from here. What’s next?
One paper describes them breeding in a human settlement in abandoned clay jars. ” While this species is not explicitly associated with infanticide, the fact that the bird lays 1-3 eggs but only ever raises one chick also implies that the species should also be closely watched by child protection agencies.
