Abstract
<p>Breeding philopatry and natal philopatry are important information for understanding their breeding ecology and population dynamics. We banded 19 parent birds and 220 nestlings of the Russet Sparrow Passer cinnamomeus in lowland open forest by Lake Ogawara in Misawa city, Aomori Prefecture during 2015–2018, then calculated the return rates based on their observation records up to 2019. Parent birds' return rate was 52.0% (n=13/25) and all returned birds bred. In fledglings, the 1st-year return rate was 5.9% (n=13/220), slightly lower than that of the other migratory passerines, and males tended to return more than females. Returning and nesting rate was the lowest at 0.5% (n=1/220) in 1st-year, and the highest at 2.5% (n=5/202) in 2nd-year. It seemed that one-year-old birds might be disadvantaged in competition for mate partners or nesting sites.</p>
