| Acute: the nails are extremely curved
and sharp-pointed, as in a woodpecker. |
|
| Obtuse: the nails are less curved
and have rather blunt points, as in a ruffed grouse. |
|
| Lengthened: the nails are rather
straight and elongated but sharp-pointed, as in the hallux nail of the Horned
Lark. |
|
| Pectinate: the nails have serrated
edges, as the middle nail of a heron (see 'Those
Amazing Birds - Good Grooming') |
|
| Flattened: the nails are so extremely
flattened and broadened as to resemble a human finger nail, as in a grebe. |
