In a hypothetical bird species, the males' circulating blood levels of testosterone stay relatively consistent over the year but occasionally spike at random times. Given this information, which of the following is the most likely explanation? This bird species likely has an endogenous pattern of testosterone production but needs to occasionally have environmental cues entrain this pattern. Since the testosterone production happens at random times, it is likely for this species that the hormone does not play a role in breeding behavior. Food is likely available year round for this bird species so it chooses to breed whenever it comes across a potential mate which can happen at any time. This bird species likely lives in an unpredictable environment so that it is not certain when sufficient food will be available for offspring
