In a warming climate, Arctic geese are rushing north
As Arctic temperatures continue to rise, migratory barnacle geese have responded by speeding up their 3,000-kilometer migration in order to reach their destination more quickly with fewer stops along the way, according to new evidence. Unfortunately, the birds' earlier arrival isn't making as much of a difference as one might expect...
Climate change is forcing geese to give up pit stops when they migrate
Barnacle geese are accelerating their migration journeys and taking fewer rest stops along the way to cope with early Arctic springs caused by a warming climate. Spring in the Arctic is starting earlier and earlier because of rising temperatures, and barnacle geese (Branta leucopsis) are speeding up their annual trip in a rush for breeding spots, with devastating consequences for newly hatched goose chicks.
Arctic wild goose chase threatens chicks as temperatures rise
Migrating geese race to warmer Arctic but are too worn out to lay their eggs early when they get there.

To help save northern spotted owls, we need to prevent kissing cousins
Biologists present a study on a Northern Spotted Owl pedigree, consisting of almost 14,200 individuals over 30 years, which determined inbreeding varies across the species' range.
Piping plovers want people to get off their lawn
A new study presents negative associations between anthropogenic disturbance (human recreational use of beaches, coastal modifications) and piping plovers on their non-breeding grounds.
It's go time for Hawaiian bird conservation, and luckily there's a playbook
A new study presents some of the best guidance to date on the priorities and actions that can be taken to help Hawaii's endemic birds. This article lays out a plan to better guide and empower conservation efforts for Hawaiian birds.
Formerly extinct ibis taught to migrate by following light aircraft...
Birds bred in captivity are led on their three-week migration south from Germany by human ‘foster parents’ in light aircraft
Leaning out of an ultralight aircraft, Corinna Esterer turns toward a flock of peculiar black birds soaring just a few metres away. “Come, come ibis,” she yells through her megaphone. Drawn by Esterer’s voice, the birds dart to the aircraft, and follow it to a field overlooking Lake Constance in southern Germany. Once on the ground, the ibis flock to Esterer. To the birds, the young woman is their parent.
For more than 300 years, the northern bald ibis has been extinct in the wild in central Europe, with small populations surviving only in zoos. But recently, it has celebrated a slow but steady comeback thanks to human foster parents who have shown the birds how to migrate south by leading the way in ultralight aircraft.Continue reading...

Today I managed to repair one of my older cameras, that had a different type of sensor to the common CMOS when it came out. I decided to go where I knew the Emu were walking today. The results were that I was able to photograph wide open and capture many subtle blue tones that modern cameras don't. So this week we are going to be in for a treat.
Below we have an emu sitting with a small pond. In the low light, we can see long shadows and lots of detail. Particularly the pale blue face of the emu. Shortly afterwards the bird noticed me and ran away. But the Encounter was well timed.
The picture turned out really well. Which is encouraging. So I have decided to give it a go for a while and see what quality photographs I can take with it. In many ways, it is a bit like a vintage car. Very cool, in its own way.
