Location: They are distributed across the whole Southern subtropical band of Catland. Much like palm island sparrows, digit sparrows have survived multiple island hopping events. They have successfully reached Soloa from East Catland, it's surrounding islands and from West Catland most of the circle islands. However they have not yet reached the most isolated Circle islands East of Soloa.
Viable Habitat: Wide range of habitats from desert and subtropical environments like hot grassland and shrubland, to cooler habitats such as the warmer temperate forests wherever winter isn't too severe.
Blue = Winter range, Teal = Resident OR Transient, Orange = Summer range
Size: 23 cm
Weight: 70 grams
Dietary Needs: Still eats a lot of invertebrates and grains in season, but also has more of an opportunistic and omnivorous diet. They may even hunt small vertebrates like juvenile lizards and mice.
Life Cycle: Mating pairs keep a larger territory than the ancestral house sparrow, especially in harsher environments where they have to travel further to forrage. The old behaviour of hopeful bachelors assisting mating pairs in hopes of being a backup, is mostly gone though still seen in greener and more prey-abundant places. Due to the extra month mating pairs can sometimes manage to squeeze out three clutches of eggs in a year, with early offspring assisting in rearing the lates. Lates have a much lower chance of winter survival but provide training for the earlies to raise the chance they will be prepared for their own first offspring. This species's range of habitation moves up and down with the seasonal cycles, and although some birds may stay well within the resident/transient zone, they might sometimes still move a little bit North or South to avoid the extremes of seasons.
Other: When they fly they stand out from other sparrows by their long tails and more distinct finger-like feathers at the tips of their wings. They have a larger wingspan to body length ratio than the ancestral house sparrow (when excluding tail) and are capable of short glides under the right conditions to save energy, maximizing the distance they can travel before they need to rest.
Although they can be gregarious sometimes, they are more independent of social contact than their ancestors and may lead some of their lives solitary or only in loose association with other birds. Travelling further by wing makes them more likely to settle new lands and less likely to stay in the same area as the digit sparrows they grew up around.
These fingertip-like extensions to the wings assist with gliding.
