What condition can lead to significant health issues if not managed in raptors?

Significant health issues can arise in raptors if conditions such as frounce, lead poisoning, and sour crop are not effectively managed.

Frounce, caused by a protozoan parasite, can lead to serious health complications if untreated, as it affects the respiratory system and overall health of the bird. Symptoms may include difficulty breathing and loss of appetite, which can ultimately lead to more severe health problems or death.

Lead poisoning is particularly concerning for raptors as they are often at the top of the food chain in their ecosystems and can ingest lead from contaminated prey or environmental sources. Lead ingestion can impair neurological functions and cause severe organ damage, making this condition a critical health risk.

Sour crop, resulting from yeast overgrowth or improper feeding, can disrupt a raptor's digestive system and lead to malnutrition or systemic infections if left untreated. Symptoms often include vomiting, lethargy, and swelling of the crop, which can be dangerous.

Given that all three conditions—frounce, lead poisoning, and sour crop—pose serious health risks to raptors when unmanaged, recognizing that they collectively lead to significant health issues supports the conclusion that the best choice encompasses all of these concerns. Therefore, the correct answer is that all
