PAKHI DEKHUN PAKHI CHINUN (Observe the Bird and recognize)...TICKELL'S LEAF WARBLER...[From a Photograph of DOLLY L. BHARDWAJ....WATERCOLOUR...A4...2013...Tickell's Leaf Warbler (Phylloscopus affinis) is a leaf warbler found in Asia. The species has a yellowish underside and supercilium. It is a common bird watchers' target in this region. The name commemorates the British ornithologist Samuel Tickell who collected in India and Burma.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 appears to be stable, and hence the species does not approach the thresholds for Vulnerable 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.
