Migration timing and routes, and wintering areas of Flammulated Owls

first_imgDetermining patterns in annual movements of animals is an important component of population ecology, particularly for migratory birds where migration timing and routes, and wintering habitats have key bearing on population dynamics. From 2009 to 2011, we used light-level geolocators to document the migratory movements of Flammulated Owls (Psiloscops flammeolus). Four males departed from breeding areas in Colorado for fall migration between ≤5 and 21 October, arrived in wintering areas in Mexico between 11 October and 3 November, departed from wintering areas from ≤6 to 21 April, and returned to Colorado between 15 and 21 May. Core wintering areas for three males were located in the Trans-Mexican Volcanic Belt Mountains in the states of Jalisco, Michoacán, and Puebla in central and east-central Mexico, and the core area for the other male was in the Sierra Madre Oriental Mountains in Tamaulipas. The mean distance from breeding to wintering centroids was 2057 ± 128 km (SE). During fall migration, two males took a southeastern path to eastern Mexico, and two males took a path due south to central Mexico. In contrast, during spring migration, all four males traveled north from Mexico along the Sierra Madre Oriental Mountains to the Rio Grande Valley and north through New Mexico. The first stopovers in fall and last stopovers in spring were the longest in duration for all males and located 300–400 km from breeding areas. Final spring stopovers may have allowed male Flammulated Owls to fine tune the timing of their return to high-elevation breeding areas where late snows are not uncommon. One male tracked in both years had similar migration routes, timing, and wintering areas each year. Core wintering and final stopover areas were located primarily in coniferous forests and woodlands, particularly pine-oak forests, suggesting that these are important habitats for Flammulated Owls throughout their annual cycle.last_img read more

Critics take aim at China’s coal plant financing in Belt and Road Initiative

first_img FacebookTwitterLinkedInEmailPrint分享The Guardian:China will host a trillion-dollar investment summit this weekend amid rising concerns that its funding of overseas coal projects could swamp efforts to keep global warming to less than 1.5C. The Belt and Road forum, which opens on Friday in Beijing, has been billed by climate campaigners as a pivotal moment that will determine whether China uses its vast financial weight to nudge the world towards renewable energy or continues to promote expansion by its fossil fuel companies.In recent years Chinese banks have become the lenders of last resort for coal projects in south Asia, Africa and the Balkans that the World Bank and other international institutes have refused to fund because this dirtiest of fuels is the primary source of carbon emissions from electricity generation.Although China has won kudos for trying to clean up its environment by cutting dependence on coal, its companies are making up for lost business at home by expanding overseas. Most of their funding comes from the Belt and Road Initiative (BRI). China says the BRI, which was launched by the president, Xi Jinping, in 2013, accelerates development in many of the world’s poorest countries and builds trade routes that benefit the global economy.Critics say it is a tool to project geopolitical power, suck up overseas resources and vent the excess capacity of a slowing domestic economy, particularly in the steel, construction and power industries. From an environmental perspective, the primary concern is that Beijing is exporting a highly polluting model of growth.Coal is likely to be at the centre of the debate. China’s banks have earmarked $36bn for 102 gigawatts of coal-fired capacity in 23 countries, according to the Institute for Energy Economics and Financial Analysis. Last year two-fifths of the country’s overseas investment was reportedly spent on this dirty energy.The biggest recipient, with $7bn, is Bangladesh, where China is vying for influence with Japan, South Korea and India. All four countries are building thermal plants in Bangladesh. Last year China Huadian Hongkong Company Limited signed a deal with a local partner to build a 1,320-megawatt plant at Moheshkhali island.More: Belt and Road summit puts spotlight on Chinese coal funding Critics take aim at China’s coal plant financing in Belt and Road Initiativelast_img read more

Walcott back in training

first_img “Good to have you back, @theowalcott!” Arsenal wrote on Twitter. Walcott’s imminent return provides a boost for Arsenal, who lost Mesut Ozil to a knee injury over the international break. Serge Gnabry, who has been out since March with a knee problem, also trained on Monday. Meanwhile, Gunners boss Arsene Wenger has revealed that Olivier Giroud is recovering well from his fractured tibia. The 28-year-old France striker broke the bone in a Barclays Premier League match against Everton in August. “Olivier Giroud is recovering very well,” Wenger told beIN Sports. “I believe he is ahead of schedule in terms of rehabilitation. The operation went perfectly.” England forward Walcott has not played since the 2-0 defeat of Tottenham in January. The 25-year-old was pictured in first-team training with the Gunners ahead of Saturday’s match with Hull. Theo Walcott returned to full training with Arsenal on Monday following his lengthy absence with a knee injury. center_img Press Associationlast_img read more

Syracuse head coach Dino Babers on victims of Tropical Storm Harvey: ‘My prayers are out to them’

first_img Facebook Twitter Google+ UPDATED: Aug. 29, 2017 at 2:20 a.m.The devastation brought by Tropical Storm Harvey has a heightened meaning for Syracuse head coach Dino Babers. Both his mother and father attended high school in the Houston area. His father is buried there. As the storm leaves an untold number of people displaced in the greater Houston area, Babers offered Monday his prayers to the victims.“My heart goes out to them,” Babers said. “I hope they’re all OK. The rest of the country rallies, like we always do, to make it easy on them and get the city of Houston back on its feet.”Tropical Storm Harvey, which made landfall in Texas Friday as a Category 4 hurricane, has so far left eight people reported dead, according to The New York Times, and many others injured. Homes and businesses have been flooded, damaged or destroyed. The United States’ fourth-largest city, Houston has about 6.6 million people living in its metropolitan area who have been affected.Babers, SU’s second-year head coach, said all of the friends and family he has been able to contact in the Houston area are OK.AdvertisementThis is placeholder text“This event is unprecedented & all impacts are unknown & beyond anything experienced,” the National Weather Service said on Twitter on Sunday. “Follow orders from officials to ensure safety.”Last fall, Babers was a preliminary candidate for Houston’s head coach opening, per the Houston Chronicle. Art Briles, who created Babers’ offense, coached at Houston from 2003 to 2007. He turned around the program during his tenure there. Then he was hired at Baylor, where he hired Babers as his wide receivers coach.Baylor, located in Waco, Texas, is about 180 miles north of Houston. Babers left the program in 2011 to become Eastern Illinois’ head coach.In 2001 and 2002, Babers coached at Texas A&M, in College Station, Texas, about 100 miles northwest of Houston.“It’s interesting because so many times you hear about those hurricanes rolling through there, it’s supposed to be really bad,” Babers said Monday. “That’s a lot of water (from Harvey). I’ve spent a lot of summers down there as a kid and there’s nowhere for that water to go.“My prayers are out to them.”The story has been updated with appropriate style.
