It's interesting to see how the various birds are holding themselves. Some of them are standing up looking around, almost like lookouts. I believe some larger birds of prey enjoy a puffin snack on occasion. Other birds are nestled up, some almost look like they've belly flopped onto the ledge.

 Notice the flying puffin in the upper right corner. Puffins have a very interesting way of landing (I've seen them in the wild).
Almost there. What I wasn't able to capture, was how fast puffins move their wings. They are not graceful gliders, like raptors, they flap rapidly so that they can stay in the air. They are not known to be long distance flyers. Migration consists of them bobbing around in the ocean.
 Notice how the puffin has landed. Similar to us, it uses its wings to try and balance itself. Increase the surface area. What is hard to see here, is sometimes puffins will just fall feet first the last couple of feet, especially in cliffed areas.
I'm wondering what the temperature is there. That may reveal why some of the puffins are nestled up whereas others aren't. I'm thinking nestling up, is a very effective way to preserve heat. However, this could also be the way that puffins rest/sleep.

Resting on cliffs
The rock appears to be smooth with little in terms of dangerous edges
Currently 11 birds on the visible area
Half the group was resting- body held low against the rock, neck pushed up against back
Resting birds close eyes for longer periods of time, still periodically blink
Half the group is moving around, one bird at edge of cliff moving head methodically from side to side (perhaps keeping watch)
Birds can be seen flying near the cliffs, perhaps trying to find food
No visible eggs- appears to be a resting place
Birds can be seen ruffing up feathers then folding them back up
One bird observed tending to feathers near breast bone

21:23
All of visible group lying down excluding one
The others have rapidly stood up and began walking around
Observed ruffling wings then folding them back together once standing up again
When ruffling feathers observed doing a slight jump
The head is the last to shake after the ruffling of feathers through the shaking of the wings
When shaking wings fly a very short distance
Frequently shake wings then fold them back up
Seem to take turns lying down for brief periods then standing up again























21:26
At times many of them seem to be lying down at a time with one or two lookouts
Others most are standing
Two birds are making noises at one another while facing each other
The beaks are opened and showed to the other bird
Seems to be either courting behaviour or rivalry
One of the birds has laid down and the other does a few more head motions and walks off
Most are standing again

21:28
Have now noticed during shaking of feathers the chest of the bird is slightly extended outwards as the back pushes inwards causing the bird to further right itself
The shaking of the wings seems to be used both for brief transportation and/or tending of the feather
Perhaps this helps to dry the feathers quicker
Molting?

21:30
When walking the birds use quick movements with their legs
They are in an upright position while walking although their bodies' are at a noticeable tilt

21:31
A huddle of 6 birds can be seen at the edge of the cliffs
They seem to be communicating with one another
The group has quickly broken up and the group has dispersed

21:32
Some birds seem to hold their body in a more upright (proud?) position than others
Is this a sign of rank?
One bird can be seen pecking another bird

21:33
A large group of arctic terns can be seen flying directly over the puffin colony
All of them are now standing
Many are shaking their wings (more then before)
Perhaps also a defence mechanism? Makes them seem larger than they are
