I wish I could say "mission accomplished" but no.. we didn't find the species that we were looking for. Me, Gabs, BobK, Cynthia and JV went looking for a particular species of KingFisher that was recently sighted and photographed.. but did not find it. Luckily there were other birds in the area that I could practice on (as I have not touched my camera in a little over three months already) These are the ones I got.. My first migrant for this year.. an Arctic Warbler  Another species, just as skittish and almost twice as hard to take a good photo of.. gerygone sulphurea This was the price catch. A not so common species.. and not as fast moving as the first two  Spotted wood KingFisher.  Thank you for taking the time to view these pics from a rusty lensman. |

Great shots! Nice to see such a juvenile Spotted Wood KF. Arctic Warbler has been split up so is this Japanese leaf Warbler, Kamchatka Leaf Warbler, or Arctic Warbler?

Great set Edu, the Spotted Wood KF is really outstanding with excellent details. |

The split happened last March and I had no idea. I would have no idea which of the three this is. But will try to get better photos for you. Thanks, Des! Edit* From the documentation I found it is still hard to tell unless we have all the three species side by side and singing in chorus but I am leaning towards the Japanese Leaf Warbler based on wingspan and yellowish underbelly. |

Edu, Don't be embarassed. It is difficult for Des, and for myself, to dice these out without having them ITH. There is also some doubt if examinandus is distinct enough to be separated from xanthodryas, and it might be just a big-billed race xanthodryas. Even if examinandus is separated this does not mean that it surely ranges in Phils. Xanthodryas does indeed range, but I doubt anyone has had time to go back and look at the philippine skins looking for surefire examinandus. The split is too new, and adjustments still have to be made. |

I'll take the 'split is too new' part, to heart ITH might not even be conclusive immediately with the song also a part of the distinction. Add to that how different should they be to be "distinct enough" right? Thank you for mentioning the bill size difference tho, I wasn't considering that at all. The joys of the avian world never stops does it?  |

Edu, I should say that I have not read the Alstrom splitting article yet. I am trying to get a hold of a copy of it. EDIT: Have now been able to download it. Will try and find time to read it through tonight. Mark Brazil is taking it for a good split, and has indicated that his book "Birds of East Asia" needs a rewrite for this. sites.google.com/site/birdsofeastasia/Home/birds-of-east-asia-updatesAnother file that shows the summer ranges of all the taxa involved (with P. borealis sensu largo, that is, pre-split). www.biomedcentral.com/content/pdf/1471-2148-10-35.pdfThere are supposedly some sonograms attributed to some of these taxa, if you can find the LP's that is: Veprincev, B. (1987) Birds of the Soviet Union. A sound guide. Record 5, Passeriformes: warblers (Phylloscopus and Hippolais). Moscow: Melodija. There is probably something of interest also on xenocanto, however, up to now the borealis files have not been subjected to the judgment of someone with the sort of expertise to consign the sonograms to the taxa. www.xeno-canto.org/asia/browse.php?query=Phylloscopus+borealisGiven that this split has now been effected, it means that we will have to pay much more attention to attempting to figure out how to identify them in the field, and from the looks of it, it may be extemely difficult just on gross morphology. A lot of birds do not vocalize in their winter quarters, one would hope that they would respond however, and it behooves us to try and find sonograms attributed surely to these now separated taxa. |
