It's awesome that new bird migration bottlenecks are still being found and described by scientists, like this one in Greece.

The IUCN species survival commission has specialist groups for bats, microbes, cranes, and dozens of other species assemblages - This week, I'm excited to be joining the group for pigeons and doves as a member.

The Trump administration has taken actions that would eliminate existing protections from about 88 million acres of public lands. Including the removal of wildlife habitat protections, the total impact of the rollbacks stretches across more than 175 million acres of U.S. land.

A map of the western United States. It shows large areas of land in green, orange, and purple, indicating areas where public land protections are being dismantled. The key indicates that green areas are National forest roadless areas, orange areas are Resource management plans, and purple areas are Lands withdrawn from mining or drilling. The title of the graphic reads, "The Trump administration is dismantling 88 million acres of public lands protections."

Celebrating a Win for Seabirds As Proposal for Rocket Test Site Is Suspended

Johnston Atoll is a tiny speck in the Pacific Ocean — approximately 1,400 kilometers southwest of Hawaiʻi. For most people, it's just a name lost in the blue expanse of the map. But for over a million...

Unlike most of Hawaii, Kaua'i doesn't have mongooses... This recent close call is a scary reminder of how important vigilance + predator control is on islands.

Migratory birds aren’t equally efficient at all speeds. A new Lund University study shows thrush nightingales fly most efficiently at 7–8 m/s – the speed they actually use on migration.

Enjoyed this @mongabay.com story about research modelling drivers of the Indonesian songbird trade. Hearing additional voices about the link between such research and solutions to stopping the trade would have been appreciated.

Great reporting on the state of wolbachia mosquito releases happening in Hawai'i to save birds edition.cnn.com/science/hawa...

Thousands of mosquitoes are being dropped by drone over islands in Hawaii. Here’s why | CNN

Native Hawaiian honeycreeper birds are being wiped out by avian malaria. Scientists think they can battle the problem by releasing more mosquitoes.

I covered a study for @mongabay.com looking into why deforestation has slowed in Indonesia and the Brazilian Amazon. The researchers found that strong political will played a big role and is often driven by public pressure and international diplomacy. buff.ly/IZPSnBN

In remote forests of west Africa, wildlife traffickers are filling orders for hundreds of hornbill skulls. The bulbous-billed birds are protected in Asia, but conservationists now worry the market has shifted to African birds.

The large leaved plant on the left of my Blue Bird of Paradise painting is thought to be a new species to science, possibly even a new family....no botanists who study New Guinea flora can identify it or put it to a family....that's crazy!!

The Center for Biological Diversity today petitioned the U.S. Fish and Wildlife Service to protect Bendire’s thrasher under the Endangered Species Act. Native to the SW U.S. and NW Mexico, they've lost ~90% of their U.S. population over the past 50 years.
