Alan's #BirdOfTheDay is #ODG
any Owl, Duck or Goose will do.
There is no Alt theme today.
#BarnacleGeese in the Netherlands are winter visitors, they breed during the summer in the cold Arctic north. However, there's also a growing resident population that has settled in the Netherlands year-round.

Bit of a wild goose chase today! All quite distant but eventually found the #TundraBeanGeese #RussianWhiteFrontedGeese and #BarnacleGeese with a large flock of #PinkFootedGeese at #Weybourne #NorthNorfolk Thank goodness for sunshine 🌞#NorfolkBirding

The #BirdOfTheDay theme is #Migratory birds that migrate to or from your country.
Barnacle geese breed on the Siberian tundra. In winter, #barnaclegeese migrate en masse to overwinter in the Netherlands.

Today’s #BirdOfTheDay theme is #Petals&Perches any bird with flowers in capture. The alt is #WhatTheFlock any capture of three or more of the same bird.
Here is my set: a #GreatTit, a #Robin, a flock of #Geese and a big flock of #BarnacleGeese

Flock of #BarnacleGeese in the field beyond my garden includes 3 birds with rings, belonging to the Svalbard-population & caught on the Solway in south-west Scotland. #Waterfowl

Just watched a #WhiteTailedEagle in a fight to the death with a #Greylag #Goose on the #loch. Poor goose lost but was too heavy for the eagle to fly with. He's got it to the bank, however. Saw the #WildIsles footage with the #BarnacleGeese but this is new to me with greylags. #Waterfowl

Diel rhythmicity of activity and corticosterone metabolites in Arctic barnacle geese during breeding
Despite the continuous daylight of the Arctic summer, barnacle geese manage to keep rhythmic behavior. Arctic summers may pose a challenge to animals relia

Gerald of Wales (c1146-c1223) is said to have developed the idea of barnacle geese generation while on an 1185 tour of Ireland. His descriptions imply that the geese are formed from goose barnacles which were really seeds. #medievalmanuscripts #medievalbeasts #barnaclegoose #barnaclegeese
![A stylised tree with blue and red flowers has black birds hanging from it by their beaks. Some of the birds appear to be stuck in the flowers. The tree is on a knob of ground with its branches hanging over greenish waves. There is a gilt rectangular background in the centre of the image and then a red background decorated with white shamrock-style outlines. It is framed by a three-sided blue outline and then a white decorated red square. Image from Bodleian Library, MS.

These particular barnacle geese are from the third version of "Topographia Hibernica" created under the supervision of the author, Gerald of Wales (c1146-c1223). #medievalmanuscripts #medievalbeasts #barnaclegoose #barnaclegeese
![A very green five-branched tree with each branch topped by a three-leaved shamrock on a manuscript page. Three of the branches have bird heads emerging from egg-like bulges and two other branches have brown-striped and tailed geese hanging from their by their tails (although they don't seem to be attached to the branches in any way). Two mature brown-striped and tailed geese, with blue wash over their bodies, are floating on the water below the tree. The geese also have brown necks and their beaks are very rounded, seeming to smile.
