The single biggest difference between a good birding morning and a quiet one near Pune and Mumbai is the month. Across every area we track, the species counts peak in January, with December and March close behind. That is the migration doing the work.
The shape of the year
October to November — arrival. Waders and wildfowl start appearing on the lakes, warblers filter into scrub and forest edge. Counts climb steeply from the monsoon low. Velhe peaks in November, earlier than everywhere else.
December to February — peak. The fullest lists of the year at every site. Winter visitors are settled, residents are still present, and the weather is as good as it gets: cold still mornings, clear light, dry tracks.
March — the second peak. Often overlooked. Numbers stay high while passage birds move back north, and resident species begin singing, which makes them far easier to find than in midwinter.
April to May — thinning out. Migrants have gone. Residents are breeding and vocal, so a smaller list is easier to actually see.
June to September — the monsoon. The counts collapse. Read that carefully: far fewer people go birding in the rain, so the records reflect observer effort as much as bird numbers. Breeding residents are at their most active and vocal. You simply cannot see much through the weather, and forest trails become difficult.
What actually arrives
The winter visitors you are most likely to meet near Pune and Mumbai:
On the water — Northern Pintail, Northern Shoveler, Garganey, Gadwall, Green-winged Teal, Common Pochard, Tufted Duck, Eurasian Coot, and waders including Common Greenshank, Wood Sandpiper, Green Sandpiper and Temminck's Stint. Pawna, Panshet and the Mulshi backwaters are the places to look.
In scrub and forest — Blyth's Reed Warbler, Greenish Warbler, Hume's Warbler, Common Chiffchaff, Sulphur-bellied Warbler, Taiga Flycatcher, Red-breasted Flycatcher, Bluethroat, Black Redstart, Siberian Stonechat.
Overhead — Montagu's Harrier, Pallid Harrier, Western Marsh Harrier, Steppe Eagle, Greater Spotted Eagle, Booted Eagle, Common Buzzard, Eurasian Sparrowhawk. The plateau grasslands around Lonavala and Kamshet are good for quartering harriers.
The scarcer ones worth hoping for: Isabelline Shrike, Isabelline Wheatear, Red-headed Bunting, Black-headed Bunting, Common Rosefinch, Cotton Pygmy-Goose, Eurasian Wryneck, Forest Wagtail.
Where the migrants concentrate
Water pulls them in. The richest winter lists are at the lake sites — Pawna (325 species) and Mulshi (326) — where open water sits beside forest and farmland, so you can work three habitats before breakfast.
Open plateau is the place for raptors and pipits; forest holds the warblers and flycatchers.

Each of those pages has a month filter — pick December or January and you will see exactly what has been recorded then, rather than a year-round list.
Planning around it
If you are choosing one weekend in the year, take one in January. If you want the best combination of numbers and birdsong, take March. If your only free time is the monsoon, go for the landscape, pick an open lake site rather than forest, and treat every bird as a bonus.
Book early for the winter weekends — they are also the busiest travel months in the hills, and the quiet properties near the good sites are the first to go.

FAQ
When do migratory birds arrive in Maharashtra? From October, building through November. Numbers peak from December to February, and most have left by the end of March.
What is the best month for birdwatching near Pune? January, at nearly every site we track. December and March are close behind, and March has the advantage of resident birds singing.
Where is the best place to see migratory waterfowl? The lake sites — Pawna, Mulshi and the Panshet backwaters. Ducks and waders concentrate on open water from November onwards.
Why do the monsoon months show so few species? Partly because fewer birds are about, but mostly because far fewer people go birding in heavy rain, so fewer records are submitted. Breeding residents are very active in those months; they are just hard to see.
