Decades of land transformation and hydrological changes resulted in the decline of the only species of apple snail native to Florida and the kite population followed suit. While the native apple snail continued declining, another species of apple snail native to South America began to appear in canals and ponds in South Florida.
The Barred Warbler , otherwise known as Sylvia nisoria , is one of those species that is aptly named if you only ever see an adult male. When the adult male bird has more than one mate, the femaleincubates the eggs and tends to the chicks alone. You know what is interesting about Barred Warblers?
There are 154 species of cuckoos in the world, and they’re all a fascinating bunch. It’s not a species you are likely to overlook, either, as it is extremely noisy, its cackling call carrying great distances. Give it a few more years and there’s a good chance that it will be split into a full species, just like the Cyprus Scops Owl.
In most years, that wouldn’t be all that special — the lake is normally where I can see the most species in a single day, so I usually go there first. These photos exaggerate the size difference between the two species, which is actually so minimal as to be almost useless for ID purposes.). Was it practicing?
Their name is no accident – Piratic Flycatchers closely monitor the nesting activities of pendulous-nesting species like Crested Oropendolas and Yellow-rumped Caciques. Targeting a nest that is just approaching completion, the flycatchers persistently annoy the builders until they eventually abandon the nest.
Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. Egg collection for local consumption still continues at lower scale. The Andean Flamingo is now protected under the Endangered Species Act of 1973. Photo: Marcio Cabral de Mora – Flickr).
One of my favorite bird species living by my house is the Juniper Titmouse. Although the Juniper Titmouse is not officially a threatened species, its numbers have been declining due to loss of habitat. But a Bewick’s Wren did build a nest, which it promptly abandoned before laying any eggs. Others had more luck.
I have observed this species many times (my eBird says 28 times this year alone) and never had one landing near me. Nowadays, it has a feeling of an abandoned construction site. Hidden from my view, it stood on a nearby tree and if it weren’t for those clumsy beats, I wouldn’t have noticed it.
Large and round-headed, smartly-striped, with a gentle gaze of mysterious black eyes, in the European south of its range this species chooses preserved mountain forests, preferably mixed deciduous and conifers. Egg-laying starts in late March to early April and they remain in the vicinity till early June.
Some 320 species have been recorded here, and in springtime it is possible to observe more than 150 bird species in a week. Due to heavy rains many clutches of Great Crested Grebes had failed, but we observed both nests with eggs (and left the area immediately) and adults with chicks, some of them piggy-backing their mothers.
It was an undeniably dank morning at the top of this island watershed, and even though we were able to discern some other species like Rufous-tailed Jacamar and the endemic Trinidad Motmot , activity was a bit slow. We were hoping for some of the more secretive species, however. From hidden perches, Blue-backed Manakins vocalized.
According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. According to Couzens, after laying the eggs, females sometimes immediately abandon their first mate and pair up with another male.
Both Elk and songbirds have the same basic method of inseminating eggs, which is one of the steps in reproduction (but not by any means the first!), Songbirds grow the offspring internally for only a very short while, and then pop out an egg, which is then cared for over a significant period of time until it hatches.
The adults of most species will still care for the chicks no matter how much you touch them. When that isn’t possible, many raptor rehabbers keep tabs on nests and will place an abandon chick in a foster nest. If the nest was in a bird house, open the house and check the damage. Do not worry about touching the baby birds.
With my recent relocation to the central forests of Trinidad, I have been afforded the incredible opportunity of observing three oft-confused species in close proximity to one another. In reality these species are rarely in the same place at the same time, however! All the more reason to keep birding!
The IOC world birdlist recognizes 90 species that bear the name “weaver” or “malimbe” Not all of these are true weavers as we will discuss below. There are currently 64 recognized species in this genus, a remarkable number indeed, and this includes the 5 Asian and 2 Malagasy species.
In total, there are eight species of hornbills in Borneo – the best place to see them seems to be the Kinabatagan River area (also known as Sukau). Another paper reviews information on Oriental Pied Hornbills raiding the nests of various bird species in Singapore and even pet bird cages.
” Funny how the difficulty of breeding a species can be illustrated in simple monetary terms. But that may have helped me to see them – the species is quite nomadic and settles wherever there is rain. Ok, back to the (presumably non-sacred, certainly non-mummified) Australian species. In a paper published in 1938 (!),
Oil begins to wash up on the beaches throughout May and June of 2010 May 6, 2010 Oil washes ashore on the Chandeleur Islands off the Louisiana coast, an important nesting and breeding area for many bird species. The babies that hatched from these eggs were released on Florida’s east coast.
The Brown Pelican and the Peruvian Pelican are closely related and once were considered the same species. Some pesticides killed pelicans directly, while DDT contamination led to thin-shelled eggs that broke under the weight of the parents. The species reached pre-pesticide numbers by the late 1990s and was fully delisted in 2009.
Basically, this species is so dimwitted, it doesn’t know how to survive. Because, Pink Pigeons are not capable of doing the tasks required to create and bring up children of the species. These endangered birds have trouble producing a fertilized egg and, even worse, they don’t even know how to build a nest so the egg survives?
