When in flight, their beauty is accentuated by black wing edges and two partial black bands near the back. Unlike their cousins, the Rock Doves/Feral Pigeons, they don’t flaunt pale rumps.
Differences Between Male And Female Stock Doves
Interestingly, male and female Stock Doves are quite similar in appearance, making it a bit of a challenge to distinguish between them at first glance.
Learn moreStarling

Starlings are often mistaken for blackbirds due to their similar size. However, these birds are distinguished by their shorter tails, pointed heads, and triangular wings.
At a distance, Starlings may appear black, but a closer look reveals a glossy sheen with hints of purple and green. Their feathers are speckled, particularly visible in their brown winter plumage adorned with bright white spots.
Starlings are known for their confident walk and run on the ground, and their flight is characterised by its speed and directness.
Differences Between Male and Female Starlings
