/ Any idea what these birds eggs are? Llanberis Pass
Crap shot I'm afraid, speckled and greenish.
They look like Blackbird eggs to me.
Someone else where said could be black birds, someone else said maybe ring ouzel
I think Ring Ouzels generally nest on or near the ground.
I reckon that location is a bit too 'mountain' for a blackbird, so my vote is for the ring ouzel - which does sometimes use trees.
They could be Raven eggs.
Been googling and they all look pretty similar, hard to tell!
Could be a Jackdaw though they often nest in cracks. A clue to their size would help,
Carrion Crow, maybe? Though the crow family - including ravens and jackdaws - tend to nest earlier in the year. Nest looks a bit elaborate for a blackbird or ring ouzel. Any idea of size of nest/eggs?
Nest diameter for a ring ousel would be <= 15cm
Not sure on the egg size, only noticed when I was a bit above.
I guess the nest was 30cm ish across.
30cm = not a blackbird, ring ouzel or raven,
*inside* diameter ?
Looks a lot like a Ring Ouzel's nest to me, and I've seen a few, though I suspect any of the Thrush family would be very similar. Definitely not a corvid! Egg size might be a better guide.
Shame this thread isn't more useful: http://www.ukclimbing.com/forums/t.php?n=585479
Nest has a different type lining material, I think Blackbirds don't do this , but apparently Ouzel's do according to images from nest construction sites.
As far as I can see the nest is in a holly tree. The eggs look to be about the size of a holly leaf, if that helps.
Yeah sorry, didn't really take in the size, but yes they are in a holly tree.
I guess creme egg type size?
No mud lining to the nest, so not one of the Thrush family. Looks a bit like a Jackdaw egg, and they do like nesting in prickly bushes or on deep cracks.
Holly leaves are (quote) 6-8cm length. Therefore by scale observed the nest would be 18-24cm.
The nest is wool lined. According to Blandford's Nesting Birds, the Ouzel grass-lines, while a raven wool-lines. But the raven doesn't normally build in a tree.
I think it is either a Rook or Raven nest. Pictures of ring ouzel nests are much more grass lined than wool lined.
I used a copy of 'The Pocket Book of British Bird's Eggs and Nests' by C.A.Hall 1946
Amazing what you pick up when swatting for your ML!
Was the nest really suspended in the tree branches or was it merely framed by them buts resting on rock/other ?
Sat on top of the tree growing out of the crag, a metre or so away from the rock face.
I still think it's a Carrion Crow's nest as per my earlier post. Rooks nest in colonies in trees lower down. And a Raven's nest and eggs would be larger. It's fun this, isn't it!
And raven nests are much bigger than 24cm across (OP said 30cm, still too small). I've climbed through the remains of a raven's nest on Ben A'an and it was huuuuge! They're big birds, not just "a bit larger than crow": BTO says they're 50% longer and weigh at least twice as much as a crow.
Jackdaw or Carrion Crow possibly but def def not Ouzel, Blackbird or Raven.
I have some close up and hands on experience with Ravens nests and that isn't one.
Cheers for the input guys.
Winds picked up here tonight so hopefully the nest is well attached to the tree!
Guesswork given the lack of dimensions etc. but Google blackbird eggs and compare cause that's what they look like to me.
That is not how a blackbird constructs a nest
so have you ever seen a raven nest in a tree?
I think my vote has come round to the crow; it's a bit upland for this bird but range can overlap with raven
Yes, ravens can nest in trees as well as rocks.
Estimating nest size at roughly 25cm (based on leaves) makes crow liklely, as jackdaws are usually colonial nesters.
I'd guess Crow or Jackdaw in that case. Not seen a Jackdaw nest in the open like that myself before, always in cracks or hollow trees, but the Crow nests I've seen have been a tad bigger and messier. As others have said, a Raven's nest is much bigger.
However, will somebody please just go and find out by watching - or will that spoil the fun?
Magpie nests have a roof over the top.
Off to Croatia climbing tomorrow and too much admin to do this afternoon else I'd nip up and get a proper shot!
