| 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. |
