Scientists have recovered the first genetic data from an extinct bird in the Caribbean, thanks to the remarkably preserved bones of a Creighton's caracara in a flooded sinkhole on Great Abaco Island in the Bahamas. Studies of ancient DNA from tropical birds have faced two formidable obstacles. Organic material quickly degrades when exposed to heat, light and oxygen. And birds' lightweight, hollow bones break easily, accelerating the decay of the DNA within. But the dark, oxygen-free depths of a 100-foot blue hole known as Sawmill Sink provided ideal preservation conditions for the bones of Caracara creightoni, a species of large carrion-eating falcon that disappeared soon after humans arrived in the Bahamas about 1,000 years ago. Florida Museum of Natural History researcher Jessica Oswald and her colleagues extracted and sequenced genetic material from the 2,500-year-old C. creightoni femur. Because ancient DNA is often fragmented or missing, the team had modest expectations for what they would find –- maybe one or two genes. But instead, the bone yielded 98.7% of the bird's mitochondrial genome, the DNA most living things inherit from their mothers. The mitochondrial genome showed that C. creightoni is closely related to the two remaining caracara species alive today: the crested caracara and the southern caracara. The three species last shared a common ancestor between 1.2 and 0.4 million years ago. "This project enhanced our understanding of the ecological and evolutionary implications of extinction, forged strong international partnerships, and trained the next generation of researchers," says Jessica Robin, a program director in National Science Foundation's Office of International Science and Engineering, which funded the study.

Brad Bird has made a name for himself as the director of new age, animated classics, like “The Iron Giant” and “The Incredibles”. Now he’s teaming up with Turner Classic Movies to share his picks for classic movie watching that will keep you busy and entertained while you’re stuck at home.

Bird has curated a list of his favorite films which will air on this season’s “The Essentials” with TCM Primetime host Ben Mankiewicz. Every Saturday from May up to January of next year, TCM will air one of twenty movies chosen by Bird. His list includes big-name classics that any movie buff will recognize, like “Casablanca” and “Dr. Strangelove”. But Bird throws in a few surprises, one being that there are no animated films on his list. Another surprising thing viewers will notice is that about a third of the films included are musicals, like “Singin’ In The Rain” and “Guys And Dolls”. With TCM’s seemingly infinite library of movie classics to choose from, Bird says narrowing it down to only twenty favorites was a challenge. According to Bird, his list comprises movies that are not only entertaining but “transcend time” and “speak in a language that is still in many ways current”.

“The Essentials” was filmed in early December, but Bird’s list is coming out during a time when movie-going is looking very different these days. The virus has put the entire film industry on pause, with studios halting production and theaters closing their doors indefinitely. In lieu of new movie releases and regular theater-going, many are taking the opportunity to revisit the classics and Bird’s list provides a starting guide for which ones should be on your watch-list.

Today on FilmWeek, Brad Bird joins us to talk about his favorite movies, what projects he has lined up, and his thoughts on how the film industry is adjusting to and getting through the pandemic.

TCM’s “The Essentials” will air on Saturdays at 8 p.m. beginning May 2. For the full list and schedule of films, click here.

Data from studies monitoring the amount of plastic eaten by seabirds suggest that levels in the North Sea are well above targets established for the North East Atlantic Ocean by OSPAR (the Oslo and Paris Convention). For the most recent monitoring period, the target amount was exceeded in well over half the birds studied.

Invasions of alien species are rising at an alarming rate, largely due to growing global trade and transport routes. Preventing the successful establishment of alien species by better understanding the factors determining success is a step toward limiting the threat of future biological invasions. Statistical modelling using observed bird invasion data — including location, event and species-level factors showed which factors were key to successful establishment by the alien species.

In Sweden, 63% of areas designated as Special Protection Areas (SPAs) for endangered birds are impacted by major roads or train lines, according to a new study. The research showed that 126 000 hectares (ha), or 4.2% of the SPAs, fall within 1 km of a road or train line, leading to a predicted 1% loss in bird abundance. The problem is greater in the south of the country, where 25.8% of land designated as SPA falls within 1 km of a road or rail line, representing an estimated 4 to 7% reduction in birds’ abundance within SPAs.

The public can help assess the human impact on wild birds through amateur ‘citizen science’ networks, according to new research. Scientists evaluated the suitability of data collected by amateur bird-watchers for long-term monitoring of European bird populations. Their findings suggest that citizen data may significantly improve the accuracy of existing official survey methods, as well as help increase public awareness of wild bird conservation.

A new tool has been developed to map the sensitivity of seabirds to offshore wind farm development. The Seabird Mapping and Sensitivity Tool (SeaMaST), currently for use in English waters, combines information on the sensitivity of seabird species to wind turbines with data on the birds’ distribution. It provides maps that can be used for both the offshore wind farm industry and marine spatial planning.

Mediterranean Marine Protected Areas (MPAs) provide important habitats for the yelkouan shearwater, a species of conservation concern, new research concludes. The study examined the behaviour of the birds at sea and found that they used MPAs extensively as foraging grounds.

Intensive irrigation of agricultural land in a Mediterranean water basin is altering the habitats of associated wetlands and changing the balance of the bird population living there, according to a recent study.

New research has found a consensus amongst experts on which environmentally friendly agricultural practices are most effective at protecting four endangered birds in Spain. Experts agreed that maintaining fallow land, preventing the use of agrochemicals and stopping agricultural practices that disrupted nesting were the most valuable measures.

Pesticides that kill mosquitoes could have indirect effects on other species, according to researchers. The study indicated that a well-known mosquito insecticide led to reduced numbers of eggs and chick survival for house martin birds.

A recent study has examined the effects of different farming practices on bird numbers and species found on farmland during the winter in six European countries. Overall, the greatest number of birds and species were on organic farms, especially when the farms were in landscapes where 80-99 per cent of the land was used for agriculture.

The public can help assess the human impact on wild birds through amateur 'citizen science' networks, according to new research. Scientists evaluated the suitability of data collected by amateur bird-watchers for long-term monitoring of European bird populations. Their findings suggest that citizen data may significantly improve the accuracy of existing official survey methods, as well as help increase public awareness of wild bird conservation.

Over 160,000 seabirds are accidentally killed by global longline fisheries each year, according to a recent study. Better monitoring and standards are needed to reduce bycatch of seabirds in fisheries, including increased on-board monitoring of bycatches and mandatory best-practice measures, say the researchers.

Planting trees and maintaining a well-balanced mix of vegetation in urban 'green spaces' can enhance the species diversity of birds and compensate for the negative effect of building, according to new research. Scientists recommend that increasing tree cover rather than limiting new development is the most effective long-term strategy to improve bird diversity in cities.

Conservation researchers have warned against acting on the findings of a previous study that argued for the eradication of several invasive birds, including the Canada goose and sacred ibis, in Europe. They suggest the results are based on anecdotal rather than scientific evidence, and that detailed feasibility studies are needed before such management decisions are made.

A recent study has found one means of complementing agricultural production with biodiversity protection by growing seeded ryegrass for silage. The seeds effectively feed many birds, such as the yellowhammer and reed bunting, throughout the winter, and the grass can still be cost-effectively used for silage if it is harvested at the right time.

Intensive farming methods have simplified landscapes across Europe, leading to a loss of biodiversity. A recent study has investigated the effects of intensive farming on plants, beetles and birds in Western European regions and found that plants and birds are particularly affected.

As the climate changes, animal species are predicted to adapt by moving northwards so they can remain within their preferred temperature range. Now, researchers have found that bird and butterfly populations are not keeping up with changing temperatures and, on average, European bird and butterfly species lag around 212km and 135km, respectively, behind climate changes.

High Nature Value (HNV) farmland is agricultural land that supports biodiversity and can be identified by its environmentally sound farming practices. New research on bird biodiversity on French HNV farmland has concluded that conservation of HNV farmland is important as well as conserving areas that were previously HNV and have undergone recent agricultural intensification.

Intensive agriculture is widely recognised as a major cause of declining farmland bird populations. New research has identified which aspects of agricultural intensification are most damaging to farmland bird numbers, examining bird populations at seven farmland sites across Europe. The researchers found that simplified landscapes created by intensive agriculture reduced bird numbers at the sites.
