This series may be a little too clinical for some but if you enjoy learning about bird biology, raptors in particular, you’ll likely find it of interest.
Watching a clumsy young hawk attempt to learn new skills always makes me feel sympathetic for its plight but I’ll admit to being more amused than anything.
Typical of potpourri there’s not much of a unifying theme here except each of my subjects has feathers in common and all five images illustrate something of interest (for me at least).
