I wonder if they were always there or if they recolonized.

Some eagle photos from our Japan in winter tour. I am heading back to do a tour here in spring, focusing on migration, local breeding birds and seabirds. But this trip is all about cranes, eagles, ducks and geese and superb food. www.alvarosadventures.com/japan-in-spr...

Elusive Californian mammal captured on camera for first time ever | CNN
Momentarily pausing after eating some mealworms, an elusive shrew’s long snout pointed skywards, unaware of the historic portrait that had just been captured.

Close up of a female Large Niltava in Thailand. That little blue slash on the neck sides is a pretty unique pattern found on female Niltavas.

I like it, "hydroclimate whiplash". These lows and highs that have been predicted to be a part of human induced climate change. It gets at the crazy nature of it, southern California goes from super wet to super dry. Setting up part of the scene for this horrific set of fires.

Here's a schematic I published in this 2021 piece to illustrate how even a modest delay in onset of rainy season in Southern California can dramatically amplify wildfire risk by lengthening seasonal overlap between dry vegetation and strong offshore winds during Oct-Jan. #CAfire
Schematic from Swain 2021 depicting how even a modest (1-month) delay in the Southern California rainy season can greatly amplify wildfire risk by increasing the temporal/seasonal overlap between critically dry vegetation and the occurrence of strong, dry offshore (downsloping) winds.

The big pigeons in New Zealand were some of my favorite land birds. The Kereru and Parea on the Chatham Islands. Huge! And colorful.

Enderby Island in the Auckland Archipelago was amazing today. Endemic birds like Auckland Teal and Shags as well as Southern Royal Albatross and Hooker’s Sea Lions. What a place!

I am in Tucson for a day, missing this... but getting info from home that it is sucking big time, and I am the one who likes the storms!! But it is wet and windy over HMB today. I only hope that the plants, soil, aquifers and all that need water get satisfaction, and that cool birds show up.

Atmospheric river ramping up. Stalling and dumping in Mendocino and Sonoma. Friday will be the day it could head farther south?

@NWSBayArea: We'll continue to see impacts linger across the Bay Area and Central Coast through Friday. The heaviest rainfall is anticipated across the North Bay, where 10-15" of rainfall are forecast. This will result in an increased floo... twitter.com/NWSBayArea/status/18592…

The Ticking Doradito, just over a decade ago it was split from the Warbling Doradito which looks like it but has a very different song. They leave Chile in winter. Presumably they go to Argentina. Yet on territory the odd "tick" sounds of this species give it the memorable English Name.

Look at this incredible satellite image of our bomb cyclone! This is such a beautiful storm, seen from space! Rarely do we get cyclones at remotely this intensity...and it's still strengthening. The NWS says its pressure is currently 955 mb, while a nearby buoy shows 74 mph winds and 950 mb. #wawx

Pincoya Storm-Petrel! We had the great luck of finding them on our recent Heart and Soul of Chile tour. I was co-author on the description over 10 years ago and sadly we still know little about this species. Our work (Norambuena et al 2024) shows it is closest to O. barroso, but distinct.

I started to do a bit more field testing of the Xinfrared lens that clips on to your phone. This is a photo of distant cows in the field. I found many European Hares, saw a fly by Southern Lapwing and a sleeping Diuca Finch. Pullao, Chiloe, Chile. The app crashed a couple of times though.

We did well today seeing 2 or maybe 3 Killer Whales near the Farallon Islands. They came to check out our boat and to look at us. What amazing animals they are.

Wagtails. Early introgression and ILS has made it difficult to create a phylogeny. The punchline is that similar looking species are not necessarily related to each other. This suggests that there was a parallel evolution of similar plumages in wagtails. academic.oup.com/sysbio/advan...

New paper and discussion on how albatross use low pitched infrasound, and move towards it. This allows the to head to areas with greater wind and waves, therefore easier travel for them! www.frontiersin.org/articles/10....
