Brown-headed Gull Over the Arabian Sea | Mumbai to Alibaug Ferry Wildlife Experience
This photograph documents a Brown-headed Gull (Chroicocephalus brunnicephalus) in mid take-off, during a ferry journey from Mumbai to Alibaug. Set against the calm yet textured surface of the Arabian Sea, the image reflects the often-overlooked wildlife encounters available along India’s coastal travel routes.
Why the Mumbai to Alibaug Ferry Route Is a Hidden Wildlife Corridor
The ferry route between Mumbai and Alibaug is not just a convenient travel connection — it also passes through an active coastal ecosystem. During winter months, migratory seabirds frequently use this corridor for feeding and resting, making it an unexpected yet rewarding route for birdwatchers and nature photographers.
The presence of open water, fishing activity, and tidal movement creates ideal conditions for seabirds such as gulls, terns, and cormorants.
Natural Habitat of the Brown-headed Gull
The Brown-headed Gull is a migratory seabird that breeds in Central Asia and the Tibetan Plateau. Between October and March, it migrates southward to coastal regions of South Asia, including India.
Preferred Habitats
• Coastal shorelines and estuaries
• Harbours and fishing zones
• Mudflats and shallow tidal waters
• Open sea routes near the coastline
Along India’s west coast, Maharashtra provides ideal wintering grounds due to its extensive shoreline and marine food availability.
Flight Mechanics and Behaviour
The flight style of the Brown-headed Gull is a study in efficiency. Its broad wings and lightweight body allow it to conserve energy while covering long distances.
How They Fly
• Strong but smooth wingbeats
• Extended gliding over water surfaces
• Low-altitude flight to scan for food
• Short running steps during water take-off
The moment captured in this photograph shows the bird transitioning from surface contact to airborne control — a behaviour commonly observed during feeding or repositioning.
How to Identify a Brown-headed Gull in the Wild
Correct identification is essential, as multiple gull species share similar habitats.
Key Identification Features (Winter Plumage)
• White head and underparts
• Pale grey wings with black-tipped primaries
• White spots visible on black wing tips
• Red to dark pink bill and legs
• Medium-sized, clean wing profile
The brown head appears only during the breeding season, which is rarely seen in India.
Behavioural Traits and Feeding Habits
Brown-headed Gulls are opportunistic feeders. They feed on small fish, crustaceans, insects, and marine scraps. Around ferry routes, they are often seen following fishing boats or floating debris where food availability is higher.
Interesting Facts About the Brown-headed Gull
• Migrates thousands of kilometres annually
• Highly adaptable to human-modified coastlines
• Uses visual scanning rather than diving for prey
• Often mistaken for other gull species due to seasonal plumage changes
Why This Image Matters for Coastal Wildlife Documentation
This image is more than a wildlife photograph. It highlights the ecological richness of everyday travel routes and reinforces the importance of observing nature beyond protected reserves.
Such sightings encourage responsible travel, awareness of marine ecosystems, and appreciation of migratory species that depend on coastal habitats.

“Seagull” is not a species either
The birds following the Mandwa ferry are not seagulls in any precise sense. India has no bird called a seagull. What you are watching is a mixed flock of gulls and terns, and separating them is the whole interest of the crossing.
What is actually behind the boat
- Brown-headed Gull: the commonest winter gull on this route. In winter the head is white with a dark smudge behind the eye; in breeding plumage a full chocolate hood.
- Black-headed Gull: very similar, slightly smaller, finer bill. The wingtip pattern separates them and it takes practice.
- Heuglin’s and Steppe Gull: the big ones, dark-backed, heavy-billed, sitting on the water rather than chasing the boat.
- Slender-billed Gull: pale, long-necked, with a distinctly sloping forehead.
- Gull-billed and Sandwich Terns: terns, not gulls — narrower wings, forked tails, and they plunge-dive rather than hover for handouts.
Why they follow the ferry
Two reasons. The obvious one is that passengers feed them, which is why the flock materialises the moment the boat leaves and disperses when it docks. The less obvious one is that the propellers churn the water and bring small fish and plankton to the surface.
On the feeding: it is worth stopping. Bread is nutritionally useless for gulls, the habit concentrates birds unnaturally, and the photographs everyone gets of gulls snatching wafers are not worth it. They do perfectly well without the ferry.
Photographing them from the deck
- Shoot from the stern where the birds hold position closest to the boat.
- Fast shutter, 1/1600 or above. Both you and the bird are moving.
- Underexpose slightly. White plumage against grey water blows out easily.
- Morning crossings put the sun behind you on the Mumbai–Mandwa run and the light is far better.
- Pick one bird and follow it rather than spraying at the flock.
The rest of the crossing
It is not only gulls. Watch for Indian Skimmers occasionally, Greater and Lesser Crested Terns, cormorants on the channel markers, Brahminy Kites over the shoreline, and Ospreys near Mandwa in winter. Dolphins are seen on the route too, though rarely.
Frequently asked questions
Which gulls follow the Mumbai to Alibaug ferry?
Mostly Brown-headed Gulls, with Black-headed, Heuglin’s, Steppe and Slender-billed Gulls, plus several tern species.
Is it a seagull?
There is no species called a seagull. They are gulls and terns of several different species.
Should I feed them?
No. Bread has no nutritional value for gulls and the habit concentrates birds artificially.
When is the best crossing for birds?
Winter, November to February, and preferably a morning sailing for the light.
