Raven. Corvus corax
- in UK, not in HK
The raven is a huge crow – by far the largest passerine (perching bird) with a wingspan of up to 1.5m.
Ravens can be mistaken for carrion crows and it’s hard judge its relative size: look out for a stronger and heavier bill, a ruffle of throat feathers and a long, wedge-shaped tail.
The best give-away for raven ID is their exceptionally deep and gravelly call.
I took these pics in Bushy park a few weeks ago...
