This morning I took a stroll around the grounds around the Dept of Public Relations, a small area of parkland which serves as the best migrant trap near my house.
Whilst checking a patch of trees where I had seen a male Siberian Blue Robin last week I heard an unfamiliar call - a rather flat, nasal "tik" repeated several times. I was really unsure what might be making the call, but knew that it was probably something unusual as I've pretty much mastered the calls of the common residents and migrants that I encounter in Bangkok. I soon located the bird making the call and was a bit surprised to find that it was a phyllosc! The bird initially gave very poor views - making me think that perhaps it was one of the species I encounter rarely (such as Claudia's Leaf Warbler), but once I got a proper look at it I determined that it was "just an Arctic Warbler".
But what about that call?! It really didn't sound like the explosive, buzzy "tzik" of an Arctic, but from memory it didn't sound much like either Kamchatka or Japanese. The bird promptly shut up, just as I got my iPhone out to make a sound recording (!) so instead I checked the calls in my playlist - it was clearly not the frog-like call of Japanese LW, but actually sounded much closer to Kamchatka than I remembered, although this bird seemed to be giving just the first part of the call (rather than the full "loose" or "dribbly" call found on the recording I had from xeno-canto). After some pishing the bird showed again and when I played the xeno-canto recording to it, it quickly moved from the high canopy of a tree some 10 meters away to the lowest branches less than two meters in front of me. It then started calling with the full version of the call, as if to confirm that I was playing it the right tape!
Whilst identification of Kamchatka vs Arctic based on plumage remains very much in its infancy, one thing that I noticed about this bird was how strikingly white the undertail coverts appeared compared with the flanks (and some of my images suggest a very light suffusion of yellow on the undertail coverts, see below).
There is still lots of work to do on these phylloscs, but some useful resources can be found in the links below:

Birders
fall into habits. They often either get into the habit of attempting
IDs on the wrong criteria (plumage and bare parts, for ex., in the case
of Pale-Sak and Arctic-Kamchatka), or they get into the habit of
throwing up their hands and giving up.
Neither
mistake is necessary anymore in the case of Pale-Sak. The research is
out there, and it is saying call is diagnosable. All that is left is for
is birders to use that new knowledge.

Great post!My wife and I are novices but have seen (what i believe to be) a female Siberian Blue Robin and Brown Shrike in the last two days. The park is a great spot. Do you know of any Pink Necked Pigeon sightings here?
Thanks for sharing such a great article, author. There are very few female dwarfs in the world. Dwarfs will captivate you not only through their impeccable talent and skill but also through their unique nicknames. Check out this article about funny female dwarf names . Here are the names of female dwarfs.

Thanks for taking the time to discuss this, I feel strongly that love and read more on this topic. If possible, such as gaining knowledge, would you mind updating your blog with additional information? It is very useful for me. I have an article about the What is the space bar click test?. The Spacebar clicker has a user-friendly UI that enables the players to efficiently begin their test and become pro at hitting the spacebar speedily. if you read it I hope it will be useful for you.

The Kamchatka Leaf Warbler in autumn is a beautiful sight. This tiny bird, with its delicate song and vibrant plumage, adds a splash of color to the season. Warblers are amazing for their long migrations and adaptability, making them a joy to observe in their natural habitat.
Exploring the Bangkok City birding scene, including sightings of the Kamchatka Leaf Warbler in autumn, offers fascinating insights. Just as understanding these migratory patterns can enhance your knowledge, seeking help, assignment writing service can improve your academic performance.
