Gray-Headed Flying Fox vs Little Red Flying Fox: common questions
What is the main difference between the gray-headed and little red flying fox?
The gray-headed flying fox is larger and tends to return to the same fixed camps, while the little red flying fox is smaller, has a distinctive reddish coat, and is far more nomadic, forming temporary colonies that can number in the hundreds of thousands before moving on in search of flowering trees.
Which of these flying foxes is more vulnerable to extreme heat?
The gray-headed flying fox is particularly vulnerable to extreme heat, with mass mortality events documented at its more fixed camps during severe heatwaves, whereas the little red flying fox's constantly shifting colonies make similar mass die-offs somewhat less consistently documented.
Why is the little red flying fox considered so nomadic?
This species tracks the unpredictable, patchy flowering of eucalypt trees across huge distances rather than relying on fixed feeding grounds, a strategy that makes its movements far less predictable than the more site-faithful gray-headed flying fox.
