Birder, Birding Guide, Pelagic operator, Writer. I am interested in encouraging more people into birding and ornithology.
I wonder if they were always there or if they recolonized.
📢 The Galapagos rail has been rediscovered on Floreana Island in the Galapagos after almost two centuries! Long-term monitoring programs are ESSENTIAL for the conservation and recovery of endangered species. 🌍🪶🧪 #ornithology

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...

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.

It took us all morning, but we finally saw a Spoon-billed Sandpiper. This is on out Thailand tour - day 1!

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.
This exact temporal sequence of events, as observed in southern California in 2024, is something we use as a prototypical example of practical consequences of wet-to-dry "hydroclimate whiplash" events--which we show are increasing due to #ClimateChange. www.nature.com/artic...

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

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

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.
As predicted, the #AtmosphericRiver has re-intensified today as it makes slow southeastward progress. Heavy rain has redeveloped from Santa Rosa southward into central Bay Area, w/narrow line of torrential downpours triggering Flash Flood Warning for City of San Francisco! #CAwx

Atmospheric river ramping up. Stalling and dumping in Mendocino and Sonoma. Friday will be the day it could head farther south?
The parent low pressure system (former "bomb cyclone") has now weakened somewhat and remains nearly stationary SW of Vancouver Island, but the strong and extremely slow-moving #AtmosphericRiver over NorCal is just getting started--and is nearly stalled out. #CAwx #CAwater [1/4]

Wow! The level of detail one can achieve now looking at traits, and genetic history. Just wow!

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.
