Grey-crowned Warbler

Phylloscopus tephrocephalus

The Grey-crowned Warbler, known scientifically as Phylloscopus tephrocephalus, is a member of the Old World warbler family Phylloscopidae. This small bird is characterized by its distinctive grey crown, which gives it its common name.

Identification Tips

When attempting to identify the Grey-crowned Warbler, look for its grey crown which contrasts with its olive-green upperparts and pale underparts. Its size and coloration are typical of the Phylloscopus genus, making careful observation a necessity for proper identification.

Habitat

The Grey-crowned Warbler is found in a variety of forested habitats, ranging from temperate forests to subtropical or tropical moist lowland and montane forests. These environments provide the necessary cover and food sources for the species.

Distribution

This warbler has a wide range across several Asian countries, including Bangladesh, China, India, Laos, Myanmar, Thailand, and Vietnam. Its presence in these areas is indicative of the diverse habitats it occupies.

Behaviour

The Grey-crowned Warbler, like many of its congeners, is an active bird, often seen flitting about in the forest canopy. Its behavior is typical of the Phylloscopidae family, with a particular affinity for dense foliage where it can search for insects and other prey.

Conservation status

According to the IUCN Red List, the Grey-crowned Warbler is classified as Least Concern. This suggests that, at present, there are no immediate threats to its populations that would warrant a higher level of conservation priority.

Taxonomy

The Grey-crowned Warbler was previously placed in the genus Seicercus. However, following a molecular phylogenetic study published in 2018, it was moved to the genus Phylloscopus due to findings that neither Phylloscopus nor Seicercus were monophyletic. This taxonomic change reflects the ongoing efforts to accurately classify and understand the relationships within this diverse group of birds.

A Friendly Place
I love using the bird app, I have a pretty good knowledge of birds. But I do have some gaps in it, so it’s nice to have a safe space to check on a sighting to confirm the species. It’s really enjoyable and I love the badges you can collect. It’s like a real life Pokémon go.

Very Wholesome App
Joined this app with a new interest in watching birds to help me find out what I was spotting. The community is very active in helping identify birds which is great and everyone is very kind so it’s just a nice wholesome community. I would definitely recommend this for any bird spotter 😄

Great app
I use this app all the time as it’s quick and easy to log individual sightings or whole birding sessions. It’s an excellent way to meet new people and the forum is full of really friendly people. The challenges are a great way to get involved and learn more about birds. Cannot recommend it enough!
