After being lucky spotting the crane chick at Slimbridge on Sunday, I can now claim a hat-trick of spottings this week. I saw Baby Bear at Chester this morning
and *drum roll* two blue-legged mantellas this afternoon

I was rather late arriving at the zoo and it was almost 10.30 when I reached the spectacled bears. Some other visitors kindly pointed out the dead tree Baby Bear was climbing (at the back and just to the left of the slope of the hill). BB was hard to see through the foliage of the other planting, but with some patience I got pretty good views with my long lens (photos downloading as I write). Binoculars would have been a useful alternative. He/she climbed up and down a bit for 20 minutes or so, but then mum came up the tree to collect him/her and they went off towards the den. I did go back several times, including just before chucking out time, but without reward.
The mantellas were much less spectacular. I saw two dark lumps in a crack in the rocks, looking a little like small sea anemones after the tide has gone out - but the nearer one had a blue stripe along it (which I assume was its thigh). Unfortunately my photos are very distorted because I had to shoot through the glass at a very acute angle. They show no more than I have described.
I was also pleased to see 2 charming crested guineafowl chicks with their parents in the Tsavo aviary, and the little male great argus pheasant was practising his courtship display on his mum, by running round and round her and then crouching and spreading his secondaries and tail feathers. This looks pretty silly as his plumage is dull brown like a female's and he is only half size, so it was a bit like a bantam displaying to a turkey hen. The adult male great argus has been moved into the aviary next door as he is moulting. I was tempted to steal one of the old secondaries that were lying on the aviary floor - but I couldn't think how to do it.
Finally in the little tank at the back of the aquarium (which was made by knocking 3 tiny tanks together) there are freshwater pipefish fry, which look like strands of button thread, 2 or 3cm long, floating horizontally in the water. The label says they are
Doryicthys deokhatoides which may be correct or it may not. I don't have a high opinion of pipefish taxonomics, but I love the animals - I hope the aquarist team can raise them successfully.
Note: the old Cattle House was closed and the horsebox was still outside, so I presume the tapirs were still inside; the sunbears were still in the Jag House; work was still going on in the new part of Islands and the Bat Cave was also closed.
