When is the best time?

Peak: 1 Dec – 31 Jan. December–January

Active from 1 Nov to 28 Feb (November to February) in a typical year.

Time of day

Arrival waves build from about 40 min before sunset and the final drop into the carr comes right at dusk; departure starts in the dark, 30–40 min before sunrise.

• Roost arrival: 45 min before sunset → 15 min after last light
• Dawn departure: 45 min before sunrise → sunrise

What will you hear?

Tens of thousands of corvids arriving in waves, calling in a rising roar, then a sudden collective drop into the wood.

Binoculars?

No binoculars needed. The waves arrive overhead and drop into the carr 200 m away; the sound is the show.

Where to go

• Buckenham Carrs, Yare valley — One of the UK's largest roosts (Mark Cocker's 'Crow Country'). Watch from RSPB Buckenham Marshes; the Norwich–Lowestoft railway runs along the reserve edge. Map
• RSPB Strumpshaw Fen — Next door; pre-roost gatherings on the marshes and a base for dawn departures. Map

How to go on your own, and what it costs

RSPB Buckenham Marshes is free and open at all hours: park in the small reserve car park off Station Road (or take the train to Buckenham station, a request stop right by the reserve) and walk the track to the river wall to face Buckenham Carrs. Strumpshaw Fen (next door) charges non-members and is dawn-to-dusk.

Cost: Free (Buckenham Marshes); RSPB Strumpshaw Fen £5.50 adult / £2.50 child non-members (2026), members free.

Field-recording notes

Arrival waves build for 30–40 minutes; a wide ambience from the marsh edge captures the layering, the final drop is short and dramatic. Trains pass roughly hourly — note times. The carr itself is private; record from the reserve tracks. Most counties have a big corvid roost — county bird clubs know where.
