Red and yellow barbet, showing off wonderful colours. This bird is on the cover of my East African bird book for a good reason! Barbets are woodpecker relatives with spiky feathers.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

Which just makes me want to share it again: www.nature.com/articles/d41...

Gladys Mae West obituary: mathematician who pioneered GPS technology

She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

Most people are worried about climate change - but most don't hear or talk about regularly.

That's why I started my free newsletter Talking Climate. Every week I share good news, not so good news, and what people can do.

If you aren't a reader yet, see below. I have 6 different ways to subscribe!

This research paper is the first time that a tipping point of a switch from a carbon sink to a carbon emission source in tropical rainforests has been identified clearly – not just for one year but for the last 20 years. Cause is a change in the local climate. www.theguardian.com/environment/...

Australian tropical rainforest trees switch in world first from carbon sink to emissions source

Researchers say carbon emissions change in Queensland tropical rainforests may have global climate implications

Common loon cruising on Kingsford Lake by Frontenac Provincial Park. Saw this fellow from a kayak, where I precariously balanced a heavy camera and lens. The loon had one foot out of the water, oddly.

We are not the first people, or the first country, to suffer under a tyrannical government that does not respect our lives, or our rights.

There is a method for how to effectively resist, and eventually topple, such a regime. We can learn from others who came before us.

This is my favorite guide.

How to help students discern fact from fiction in the media they consume ehe.osu.edu/news/listing...

The stake are high! Teach:

- Teach lateral thinking
- Consider multiple sources
- Ask the hard questions (who created content? what was motivation?
- Teach to using primary sources

How to help students discern fact from fiction in the media they consume

The stakes for teaching students to not fall victim to digital rogues could not be higher.

Good to meet with Prime Minister Kristersson today, to discuss the growing partnership between our nations.

We’re leveraging each other’s strengths — in clean energy, critical minerals, and defence — and working together in shared missions, like bolstering security in the Arctic.

In an era of great power rivalry, Canada is choosing to be principled and pragmatic. To name reality, to act together, and to build what we claim to believe in.

For #longbeaks #birds, here is the saddle-billed stork, a hunter of little vertebrates in wetlands of Africa. This fellow is from Lake Manyara, Tanzania.
#nature #wildlife #photography #nikon #naturephotography #wildlifephotography #tanzania #africa

The very large saddle billed stork is hanging out in the former freshwater wetland adjacent to the alkaline Lake Manyara. This lake expanded following long rains and a very intensely wet year, and this wetland is now under the alkaline waters of Manyara.

A moment in nature today… Green sea turtle rising for breath from a bed of sea grass. Darkening times but trying to find a measure of peace in such moments. Hope others can too.
