Emperor penguins have joined the list of wildlife endangered by global warming, the International Union for Conservation of Nature announced on Thursday.

Populations are declining as climate change causes the sea ice the birds need for survival to retreat, according to researchers.

The BBS is a phenomenal achievement. But trends for 'my' main study species are all very bleak for 1995-2024 population change: Marsh Tit: 53% decline Willow Tit: 92% decline(!!) Wood Warbler: 82% decline Wood Warbler is already generally considered irrecoverable in England. #ornithology

Snowpack around the Lake Tahoe Basin is receding quickly and is now confined to only the highest elevations. It is not even April yet. Looking like we are going to have a very water-limited summer. Will be interesting to see how the insects and birds respond.

American Wigeon (Mareca americana) male spending his winter with us in Reno. He even smiled for the camera 🦆😃 Soon he’ll be on his way to his breeding grounds, probably north of us - possibly all the way in Alaska. Always love seeing these guys, and equally as much, hearing their cute squeaks #birds

I think my worldview can be summarized by the following three points: ____ people are people too, and should be treated as such ❤️ Earth is our only home and is worth saving 🌍 Diversity is essential for a healthy ecosystem/society 🌈 It’s really that simple.

Today, in my town of Reno, NV, students from nearly all high schools and even some of the middle schools participated in a walkout to protest ICE. I’m so proud of them ❤️ We should listen to them - they read the history books most recently so they know what’s at stake.

Everywhere I look I see women leaving academia for one reason or another, and many of these reasons are less relevant to male counterparts. Obstacles like longer review times are certainly not helping, especially in a career where success and progress are measured in publications!

Streaked Flycatchers (Myiodynastes maculatus) are large flycatchers native to Central and S. America. On first glance they appear rather drab, but they have beautiful cinnamon tails and stunning facial markings. While they mostly eat insects, they are also known to eat fruit and even small lizards 🪶

An intense look from a very tiny northern pygmy-owl (Glaucidium gnoma). These owls weigh less than an American robin (~70g)! They are unusual among the owls because they are diurnal, meaning they hunt and are most active during the daytime. They prey mainly on small songbirds and mammals. #birds

Today 14 scientific societies in #ecology #evolution and #marineScience are publishing the results of a survey that finds negative impacts of federal policies on food security, flood mitigation, infectious disease preparedness, and wildlife conservation: 🧪👩‍🔬 www.firsthandaccounts.org/impacts/2025...
This infographic describes the main results from a survey of members of 14 scientific societies. There is a pie chart showing that both academic (58%) and non-academic (42%) responded to the survey. It lists statistics: 85% of respondents reported uncertainty about the future; 71% reported federal training programs were "very" or "extremely important"; 83% reported negative impacts or irreparable harm on their field of science. There is a word cloud summarizing open-ended responses with the largest words "student research fund federal grant". Eight major themes in the responses are listed: disruption of research with societal important; concerns of closure of the USGS Bird Banding Lab; Early Career Bottleneck; Restricted Freedoms including travel and speech; Decline in Government Efficiency and Expertise; Concerns about Biased/Removed Data and Data Gaps; Concerns about the Ability to Meet Legal Mandates; and From Positive Impact to Irreparable Harm. There are icons for each participating society and a QR code for website and data availability.
