| Scientific name | Common name | Performs broken-wing display? | Length of incubation (days) | Incubation duty | Maximum number of broods per year |
|---|---|---|---|---|---|
| Setophaga caerulescens | black-throated blue warbler | Yes | 13 | 1 parent | 3 |
| Spatula cyanoptera | cinnamon teal | No | 25 | 1 parent | 1 |
| Haematopus ostralegus | Eurasian oystercatcher | No | 28 | 2 parents | 1 |
| Zenaida macroura | mourning dove | Yes | 15 | 2 parents | 7 |
In an extensive review of existing literature, Léna de Framond and team cataloged the prevalence of broken-wing display—a defensive behavior observed in Charadrius semipalmatus (semipalmated plover) and many other species—throughout the Aves class. Documentation of the display in 285 species across 52 families suggests the behavior likely evolved independently multiple times, prompting the team to consider ecological and life-history characteristics with hypothesized associations to the behavior’s emergence, including traits related to reproduction investment and future reproduction potential.
