Rafnuss,
Is it possible for you to process the 1st photo to enhance the image ? (for sharpness, colour saturation, and better clarity) ?
I can't really tell for sure the colour of the eye ring from the initial photo.
Without looking at photos, one of your best bets was your impression - an Australian Hobby will seem much lighter, and the wing beats seem sharper and higher frequency and tippy - like they are flicking the wingtips. The peregrine, even when fully powering on seems more effortless like a tractor beam is pulling it forward across the sky, even though the wing beats seem heavier. Of course both falcons do all manner of soaring, banking, and gliding behaviors too.
I will agree with others here that your bird does look quite solid and blocky. A female Australian Hobby is not that far behind (dimensional size-wise) a male peregrine falcon. The female Hobby is noticeably larger than the male Hobby, with relatively blockier and larger head, beak, and talons ..... though the female Hobby will still seem less 'stout' than the male peregrine. The male Hobby looks distinctly smaller and more lightweight than both, and the female peregrine noticeably blockier with relatively more massive beak, feet and talons than the male peregrine.
Peregrines I have seen (even down south east here) have one of two colour schemes - 1. The classic dark bluish black helmet, slate grey wing uppers, and cream or bone coloured torso front with bluish black horizontal barring. Eye ring, cere, legs, and feet are a bright yellow. 2. A second type has a matt black helmet, more dark browny-black slate wing uppers, and a rusty warm buffy cream torso front with black horizontal barring. Eye ring, cere, legs, and feet are an orangey yellow. Juveniles of both types have a more buff torso front with more motley barring, and bluish-grey eye ring and cere.
Australian Hobbys have a more dark bluish dark brown helmet, less defined, with a distinct buffish collar up the side and toward the back of the neck. The upper wings are more bluey slate, and the torso front more buff with vertical very dark brown streaking. Eye rings and ceres are bluish grey. Juveniles again are more buffy and mottled.
I am undecided on your bird - the helmet look very black and solid, and the beak large - indicating peregrine. If it is an Australian Hobby then I would say it is a female, and one that may have recently eaten (crop looks enlarged, and body full).
Perhaps a better processed photo may help us?
