Reproduction, Nesting, and Life Cycle

Reproductive strategies of amerikaanse dwergstern; amerikanische zwergseeschwalbe; antillean tern; antillen-seeschwalbe; charrancito americano; charrán mínimo; least tern; meuchi chikitu; petite sterne; spratt gull; stèrnchi chikito; amerikadvergterne; little tern; trinta-réis-miúdos are diverse and adapted to environmental conditions:

Breeding Season: Timing of reproduction is typically synchronized with peak food availability to support energy-demanding egg production and chick rearing. In tropical regions, breeding may occur year-round. Courtship and Pair Formation: Mate selection often involves elaborate courtship displays including songs, visual displays, aerial performances, or gift-giving. Some species form lifelong pair bonds while others are seasonally monogamous or polygamous. Nesting Behavior: Nest construction varies dramatically among species, from no nest (ground-laying) to intricate woven structures, mud nests, or cavity nesting. Nest placement balances accessibility with protection from predators and weather. Eggs and Incubation: Clutch size, egg appearance, and incubation duration are species-specific traits. Incubation may be performed by females, males, or both parents, maintaining optimal temperature and humidity. Chick Development: Altricial chicks hatch helpless and require extensive parental care, while precocial young are mobile and relatively independent shortly after hatching. Fledging time and post-fledging care vary.

Conservation Status and Threats
