Friday mystery object #351 answer

 

Last week I gave you this unusual object to have a go at identifying:

There were a variety of clues and suggestions (some beyond my ken) but they tended towards identifying this as the nest of a Tailorbird. In fact salliereynolds even provided a video of the Common Tailorbird in action:

This was pretty darn close (excuse the pun), but the nest structure isn’t quite what I would expect from a true Tailorbird in the genus Orthotomus, plus I had a bit of extra information on a secondary label suggesting that this nest is from Sierra Leone (although the quality of the handwriting on the primary label made it indecipherable, so I’m not sure if it mentions the species or something else entirely):

It’s worth noting that most of the true Tailorbirds are in Asia (mainly the Philippines), but in Africa there are some closely related birds that build similar nests that are a little more similar to the mystery object. A birds in the genus Cisticola is the most likely culprit in Sierra Leone, and I’ve seen Red-faced Cisticola Cisticola erythrops (Hartlaub, 1857) nests that match the structure, leaf selection and construction technique used here, so I think it will be something along those lines, but I simply can’t be sure.

This is a great example of why good, clear handwriting is really important in a museum setting. A bit of time spent with examples of Capt. H. W. Long’s writing might help decipher the original note, assuming such examples exist. Or, it may be that there’s a talented palaeographer who can read the original  note – if you have any thoughts your suggestions would be welcome!

Last week I gave you this mystery bird as my 350th specimen for identification:

It wasn’t particularly easy, although that oddly preserved crest did help narrow it down.

As Wouter van Gestel pointed out, the general shape of the bird, particularly the legs and sternum, suggest that it’s a passerine. There are quite a lot of crested passerines, from Crested Tits to Crested Jays, but the bill shape on this specimen only matches a few.

Bob Church worked it out and left a nice cryptic clue:

Well, I could be wrong and might bomb this one, but perhaps if I wax poetic, I could wing it a bit.

Taking bomb, wax and wing clearly relates to the waxwings in the genus Bombycilla.

For the full species definition there was a response on Twitter from the Scarborough Museums Trust Collections Team:

“Chattering silk-tail” is a direct translation of the scientific name Bombycilla garrulus – which is spot on!

They get their common name from the waxy red tips on their secondary feathers and their ‘Bohemian’ lifestyle – in the 19th Century sense of them being wanderers. They migrate thousands of miles and have a huge distribution across the Northern Hemisphere.

I find their silky plumage and rich but quite blended colouring particularly beautiful – something that is a bit lacking in the mystery specimen.

This week marks a minor milestone for my blog – the 350th mystery object. Thanks to everyone who comes to take a look at the specimens I’ve been sharing from the various museums I’ve worked in over the years. I hope you’ve enjoyed them!

This week I have a funky specimen from the Dead Zoo for you to have a go at identifying:20170213_113309-01.jpeg

It stands around 17cm high, including the crest, which is a particularly striking feature to be preserved on a skeleton.

Any ideas what this is? As usual, you can put your questions, observations and suggestions in the comments below. Most importantly, have fun!

Friday mystery object #349 answer

Last week I gave you this long, pink, wrinkly specimen to have a go at identifying:

There was a lot of discussion about whether it has limby bits, fins, flaps left over from damage during preparation or some other unnamed and dubious appendages. I’m relieved to confirm that it has limbs – albeit rather reduced limbs.

 

The limbs are important, since they allow us to rule out all the legless groups of similar critters, like Caecilians (limbless amphibians), Synbranchidae (swamp eels), Amphisaenidae (worm lizards) or of course snakes (not that any self-respecting snake would have a face that looks like it belongs to a poorly made sock-puppet).

The state of the legs, especially the very reduced state of the front limbs, also allows us to rule out a variety of Olms, Sirens and other Salamanders – except for one odd little genus called Amphiuma.

There are only three living species of Amphiuma – the One-toed, Two-toed and (believe it or not) Three-toed. Someone in the past hedged their bets and labelled the mystery specimen as follows:

Since the Three-toed salamander is Amphiuma tridactylus Cuvier, 1827 and the Two-toed is Amphiuma means Garden, 1821 this label is misleading.

The Three-toed salamander does have three visible toes on the forelimb and this specimen clearly doesn’t – with just a vestigial wriggly bit (that doesn’t make it the One-toed salamander however, as they are smaller and they have an even more reduced hind limb). So this is the Two-toed Amphiuma means.

Finally, it might be a bit confusing that the mystery object is a pink thing, while the living animal is a mottled muddy colour. That’s just an artefact of it being preserved in ethanol for the last 125 years. Trust me, no-one looks good after that much exposure to alcohol.
