Catch one of Delhi’s first migratory birds, the Greenish Warbler

The Greenish Warbler is a hen that is available in from Europe, halts in Delhi, after which flies off to South India

It was August 22, 2020, and with the pandemic journey pointers barely lifted, I made a rapid sprint to Gurugram to meet up with a former intern who was leaving for Oxford College. I hadn’t anticipated to listen to the shrill, loud disyllabic ‘chee-wee’ cry of the Greenish Warbler, in a stray wild patch outdoors her high-rise condo. I silently excused myself and recorded the decision of this dainty medium-sized (10 cm) warbler on my cellphone.

A couple of birds are pretty straightforward to identify, owing to their dimension, color, and behavior, however not this one, of the leaf-warbler species, the members of that are so comparable in look it’s troublesome to distinguish one from the opposite: brightly colored and slim in look.

The timid behaviour of inhabiting the canopies of timber (the place they feed on bugs) and flittering round from department to department, usually makes a skittish hen just like the Greenish Warbler (Phylloscopus trochiloides) exhausting to identify by the thick foliage. The time period Phylloscopus has been derived from the Greek phrases phullon that means ‘leaf’ and skopos that means ‘seeker’.

The Greenish Warbler is among the earliest migrants to journey from its breeding grounds in Europe to our area late in August, earlier than transferring additional to South India in November, although just a few stray birds do stick round till later.

The hen has a pale greyish-olive plumage above and uninteresting clear white breast, with a dusky gray wash to the edges. Like most arboreal warblers feeding within the cover of timber, the Greenish Warbler has skinny legs (darkish on this species) in contrast to the stouter legs in different kinds of warblers that choose to feed on floor. The spiky invoice and reflexes assist them catch bugs in air.

The species has a robust clearly marked head sample with an extended yellowish-white supercilium (eyebrow), distinguished white ring across the eye, and a broad eyestripe. Usually, they’ve a brief square-shaped tail and the wings have a single quick, fairly broad yellowish-white wingbar. Typically there’s a second narrower wingbar troublesome to see on the sector.

Each sexes are comparable wanting, and so they’re principally discovered singly or in pairs. They principally nest in shrubs, to keep away from predatory assaults in excessive timber.

Though present in a wide range of habitats and altitudes, they’re forest-dwellers. Within the metropolis, search for them in wooded areas: gardens with outdated dense timber, and locations like Vasant Kunj, Saket, and North Campus.

A method of figuring out them is to search for fidgety birds that flick their wings and sometimes their tails. One other means, is to pay attention for the ‘chee-wee’.
