American Redstart is a warbler, readily identified by the males black and orange color pattern. They sing a variety of songs during the spring and summer. This male is giving the most common variation, sometimes described as ‘see-see-see-Oh.’

There is an organisation Stichting Vrienden Natuurbehoud Suriname.
Already in 2009, they had published Annotated Checklist of the Birds of Suriname.
The cover depicts a Guianan cock-of-the-rock, another one of the over 750 Surinamese bird species.

An Inside Look at the Exotic Animal Trade: Profiles by VICE
19 May 2014
In the United States, regulation of private ownership of exotic animals is determined by each state, allowing for loopholes and oversight. Animals are bought and traded through auctions, backyard breeders, illicit online sales and more. The industry is growing right in our backyards.

New report shows shocking extent of UK exotic pet trade
Two animal welfare organisations are calling for a Government review of the exotic pet trade, as a worrying new report reveals the huge scale of unsuitable and potentially dangerous animals widely available to buy online.
The One Click Away report, compiled by Blue Cross pet charity and the Born Free Foundation, found that at any one moment across a sample of just six websites, there were around 25,000 adverts offering more than 120 types of exotic animals for sale online. Animals for sale included reptiles, exotic birds and primates, many of which are particularly vulnerable to welfare problems when kept as pets. With little or no regulation of online sales, the charities are concerned for the health and welfare of the animals available to inexperienced owners, as well as the safety of the public and want to see laws surrounding the sales of exotic pets brought up to date.
Very few adverts offered advice on the animals’ history or how to care for them, potentially leaving new owners unaware of health or behaviour problems and sellers are not required to state whether an animal could be harmful.
Steve Goody, Blue Cross Deputy Chief Executive, said: “This report shows the shocking scale of the exotic pet trade and the urgent need for action. For the inexperienced, it can be difficult to care for many of these animals in a domestic environment and as a result the animals’ welfare often suffers.
“With ever-increasing demand for more and more unusual pets and the huge growth in internet sales, it is high time for the Government to take action to ensure that this exotic pet industry is properly regulated.”
Although existing laws in Britain – including the Animal Welfare Act 2006 and the Pet Animals Act 1951 – offer all pets a certain level of protection, there is confusion over their application and enforcement. The Pet Animals Act 1951, which controls the sale of animals in pet shops, was drafted long before the advent of the internet or the growth in popularity of exotic pets and, the charities are convinced, is no longer fit for purpose. Blue Cross and the Born Free Foundation would like to see this legislation amended to ensure that it becomes relevant and effective today.
Chris Draper, Programmes Manager for Captive Wild Animals at the Born Free Foundation said: “It is truly shocking how many exotic animals and of such diversity are available online, with so many advertised incorrectly or incompletely and with no indication of their often complex needs. The Government needs to review the Pet Animals Act as a priority to ensure people are made aware of the issues related to buying exotic pets online and we should urgently examine how these animals are faring in the pet trade.”
Angela Smith MP said: “As this report shows, the welfare of thousands of exotic pets is at risk and we need to act to change the situation for them. I am fully committed to raising awareness of this important issue and getting it onto the Government’s agenda.

First feathered dinosaur from North America introduced by Darla Zelenitsky

Canadian researchers discover fossils of first feathered dinosaurs from North America.

The links between dinosaurs and birds keep getting stronger: skeletal structures, feathers—and now nests. Whereas some dinosaurs buried their eggs crocodile-style, a new analysis suggests that other dinosaurs built open nests on the ground, foreshadowing the nests of birds.
Interpreting the fossil record is always tough, but analyzing trace fossils such as nests is especially daunting. Those structures, and the materials used to make them, usually aren’t preserved, says Darla Zelenitsky, a paleobiologist at the University of Calgary in Canada. When paleontologists do find a nestlike structure that includes material such as sticks or other vegetation, the question arises: Was this stuff part of the original nest, or just carried there with the sediment that buried the nest and helped preserve it?
To gain insight into dinosaur nesting habits, Zelenitsky and her colleagues studied the most durable parts of nests—the eggs themselves. (Being largely made of the mineral calcium carbonate, they’ve got a head start on fossilization and are sometimes incredibly well preserved.) In particular, the team looked at the size and arrangement of small pores in the ancient shells, because those details are telling in modern creatures.
In crocodiles’ buried nests, the heat needed to incubate the eggs comes from decomposition of overlying organic matter or the sunlight absorbed by the soil. Plus, in buried nests airflow is somewhat limited, thus requiring eggs to be relatively porous to help increase the flow of oxygen into and carbon dioxide out of the eggs. But birds that brood in open nests can get by laying eggs with fewer or smaller pores.
So the team compared the porosity of eggshells from 29 species of dinosaurs (including large, long-necked herbivores called sauropods; bipedal meat-eaters called theropods; and duck-billed dinosaurs) with that of shells from 127 living species of birds and crocodiles.
Most of the dinosaur eggs were highly porous, suggesting that they buried their eggs to incubate them, the researchers report online today in PLOS ONE. But some of the dinosaur species in one group—a subset of well-evolved theropods considered to be the closest relatives of modern-day birds—laid low-porosity eggs, which suggests they incubated their eggs in open nests.
“This is a well done paper; the results make a lot of sense,” says Luis Chiappe, a vertebrate paleontologist at the Natural History Museum of Los Angeles County in California. The findings, he says, line up other studies suggesting that some birdlike dinosaurs were warm-blooded, which would have enabled them to incubate eggs in an open nest rather than depend on rotting vegetation or sunlight. Chiappe adds that the trend toward open nests could have allowed some dinosaurs to take another step toward birdlike nesting by moving their nests into the trees.
But considering only two types of nests—open versus buried—may be too simplistic, suggests Anthony Martin, a paleontologist at Emory University in Atlanta. Some dinosaurs—like a few of today’s birds—may have nested in burrows, which could have offered the stable temperature and protection from predators of a buried nest but resulted in low-porosity shells. Also, covered nests come in different types: Loose vegetation piled atop a buried nest can have a lot of airflow through it, allowing eggs to have relatively small pores, whereas eggs buried in soil or similar materials might not breathe as well and thus require larger pores, he notes. Nevertheless, Martin adds, the team’s study “is a good first start toward answering the question about what early dinosaur nests looked like.”
