जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Dependent on healthy, uncontaminated coastal wetlands and estuaries for feeding. Wades in shallow water whilst foraging. Forms colonies. Piscivorous. In Florida Bay, natural feeding supplemented by "panhandling" association with humans where they feed on bait fish from locals and developed begging behavior from residents. In Stanley Park Zoo in Vancouver, British Columbia, a large colony is able to persist in close proximity to human activities for over 78 years. In Florida Bay, population decline of 30-40% due to hurricanes were linked to nesting and foraging habitat degradation (Ref. 87784).
