The house sparrow's flight is direct (not undulating) and flapping, averaging 45.5 km/h (28.3 mph) and about 15 wingbeats per second. [107] [126] On the ground, the house sparrow typically hops rather than walks. It can swim when pressed to do so by pursuit from predators.
The vesper sparrow is 14–16 cm (5.5–6.3 in) in overall length and weighs 19.5–28.3 g (0.69–1.00 oz). [8] Adults have light brown upper-parts and light under-parts, both with darker streaking. There are three features that are unique to the vesper sparrow. The first is the presence of a small, white ring surrounding the eyes.

A small raptor, with a height of about 30 cm and wingspan of 72 cm, the rufous-breasted sparrowhawk is named for its distinctive rufous-coloured underparts, which can be seen both perching and in flight. It is dark grey slate-brown above, including the head, with a black bill and eyes that are yellow at all ages. [3]
The flight is a characteristic flap-flap-glide, with the glide creating an undulating pattern. [22] This species is similar in size to the Levant sparrowhawk, but larger than the shikra (the calls are however different [23]); the male is only slightly larger than the merlin.

Sparrowhawks rely on stealth and surprise to catch their prey, hunting in flight or bursting from a concealed perch among foliage. [10] Most prey weighs less than 100 g and sometimes over 200 g. It forages by short-stay perch hunting from a concealed position in foliage, punctuated by short tree-to-tree, often undulating flights. [ 10 ]
