Barn Owl (1 Viewer)

Tif Update October, 2016


Barn Owls:

Based on Aliabadian et al. (2016), the American Barn Owl, Tyto furcata (both North and South America, and Hawaii) has been split from Common Barn Owl / Western Barn-Owl, Tyto alba (Europe, Africa, and the Middle East). Its English name has been simplifed to Western Barn Owl. The Eastern Barn Owl, now named Tyto javanica instead of Tyto delicatula, now includes all subspecies from Pakistan and India through Australia and into the Pacific.
[Strigidae, Afroaves II, 3.05]

[pdf here] [supp. info.]

An interesting read, albeit it's a pity that they included Wink et al's sumbaensis and furcata cytb sequences in some of their analyses without checking them a bit more closely. A simple look at the first alignments produced by a BLAST search on the sumbaensis and furcata sequences would have immediately shown that there was a problem.

(Fig. S1 [in the supporting info pdf] offers an interesting example of the effects that this type of sequences can have on a tree reconstruction. sumbaensis and furcata belong respectively to the Australasian and American groups of barn owls, but Wink et al's cytb sequences both have their first 200-and-something base pairs that is [mainly] storm-petrel DNA. These sequences are attracted both towards their own respective barn owl group, because of their genuine Tyto part, and towards each other because of the storm-petrel DNA they share. Here, this resulted in the Australasian and American groups appearing sister with high level of support, each with its own chimeric sequence in basal position and de facto imposing a rooting to the group. Neither the sister-group relationship, nor the orientation of the two groups, and thus the relationships within them, can be trusted. [In particular, the rooting of the group including the sumbaensis sequence is obviously spurious.] IOW, the inclusion of these two chimeric sequences affected strongly a large portion of the reconstructed tree, with effects that went very far beyond their own position in the tree.)

But despite this, with this paper's data added to what was already available, it now seems wholly unquestionable that javanica (as well as stertens) belong with the 'delicatula' group, and outside of the alba group. Time to revisit the IOC/H&M species limits?

(I've attached single-gene trees generated from all available [and reasonably long] 16s, cox1, cyt-b and rag1 sequences of Tytonidae. Rag1 evolves slowly, and has little signal within Tyto; all three other genes clearly delineate three groups of barn owls, with S Asian birds all clustering with Australian birds.)

This doesn't looks like a very unusual scheme to me -- i.e.: "Last-name-1, First-name-1, First-name-2 Last-name-2, First-name-3 Last-name-3," etc...
The SACC reference list uses a similar system, but with initials of first names only: http://www.museum.lsu.edu/~Remsen/SACCBiblio.htm

They will need to change the English name of Tyto alba to something other than 'Western' Barn Owl now.

Any suggestions?

Need to? A name is just a name, and this one probably makes perfect sense if you are living in India. :-O

Is the Eurasian bird more inclined to nest in old buildings than other forms?

If confirmed, may I then suggest 'Barn Barn Owl'
