# Animal articles

Species profiles, animal behaviour and source-backed discoveries.

- [Mallard identification: females, eclipse males, lookalikes](https://animalchecklist.com/animal/mallard/article): A brown duck is not always a female Mallard. Compare bills, wing patches and eclipse plumage, with sourced lookalike clues and honest identification limits.
- [European robin: juveniles, red breasts and field clues](https://animalchecklist.com/animal/european-robin/article): A juvenile European robin can lack the familiar red breast. Compare the plumage, learn what a photograph cannot prove and observe without disturbing the bird.
