Spoonbill Video Quiz
The drainage and development of south Florida has negatively impacted the wetlands roseate spoonbills need to survive.
Question 1 Explanation:
The reduction of freshwater flow from the volumes the southern Everglades historically received has altered the ecosystem and reduced the prey available for wading birds.
Roseate spoonbills locate their prey by sight.
Question 2 Explanation:
Spoonbills are tactile feeders, meaning they feel for prey items with their sensitive bills, which snap shut when they encounter a small fish or crustacean.
Nesting efforts are timed with the Florida wet season, when water levels in the wetlands are high.
Question 3 Explanation:
Because roseate spoonbills feed by tactolocation, they rely on the concentration of fish that occurs when the water recedes in the dry season in order to find enough food to feed their chicks.
The energetic demands of spoonbill chicks require parents to have constant access to productive feeding grounds.
Question 4 Explanation:
Spoonbill chicks grow rapidly, and the ability for both parents to make repeated trips to foraging wetlands with abundant food is necessary for chick survival.
The nesting success of roseate spoonbills in Florida Bay is an indicator of the health of the southern Everglades wetlands.
Question 5 Explanation:
Successful nesting efforts require ideal wetland conditions and abundant prey, therefore indicating the ecosystem is healthy and also able to support other species of wildlife.
Brown pelican, osprey, and bald eagle populations in Florida Bay have increased.
Question 6 Explanation:
Populations of these fish-eating birds in Florida Bay have also decreased, indicating an overall reduction in available fish and an ecosystem in decline.
