The striated grassbird (Megalurus palustris) is an "Old World warbler" species in the family Locustellidae. It was formerly placed in the family Sylviidae. It is now the only species placed in the genus Megalurus. It is found in Bangladesh, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Pakistan, the Philippines, Thailand, and Vietnam.
Noisy and conspicuous, often sitting and calling exposed on tops of grasses, bushes and telephone wires. Note streaked crown and streaked upper breast. This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
The genus Megalurus formerly included additional species. A comprehensive molecular phylogenetic study of the grassbird family Locustellidae published in 2018 found that Megalurus was non-monophyletic. In the resulting reorganization, five species were moved to the resurrected genus Poodytes and four species were moved to Cincloramphus, leaving only the striated grassbird in Megalurus. Wikipedia →

Possible
About 30% of wildlife watchers report a Striated Grassbird sighting in Manila on a given day, based on 1,053 verified sightings from GBIF citizen-science data. It is the 23rd most-seen of the 191 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May and June
In those months about 40% of wildlife watchers report a Striated Grassbird in Manila on a given day, against about 20% in July to December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Striated Grassbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 10
Of the 10 cities where we can rate Striated Grassbird sightings, Manila ranks 2nd at about 30%. The best odds are in Chattogram (Bangladesh, about 60%).
GBIF citizen-science records
It is estimated from how often the Striated Grassbird is recorded against all the birds logged in Manila (1,053 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
