"本報では，信州大学農学部附属AFC手良沢山演習林における最近10年間（2004～2013年度）の鳥類調査データを概説する。調査は，同一ルート，同一査者によるラインセンサス法で実施した。年間の調査頻度は，繁殖期２回（落葉広葉樹の展葉前と展葉後），越冬期２回（積雪の前と後）の計４回とした。その結果，22科50種の鳥類が確認され，内訳は留鳥26種，夏鳥14種，冬鳥10種であった。常在度の高い鳥類は，ミソサザイ，カラ類（シジュウカラ，ヤマガラ，コガラなど），エナガ，ヒヨドリ，カケスなどであった。前半５年間（x）と後半５年間（y）に大別して種ごとのデータを比較すると，両者の関係は出現頻度，確認個体数ともy＝x に近い回帰直線となり，R2＞0.8と高度に有意であった。回帰直線からの乖離で判断すると，ガビチョウ（2009年に新規参入）やエナガの増加が目立つ一方，センダイムシクイ，クロツグミ，ハシボソガラス，シジュウカラなどの減少が目立った。手良沢山演習林全体の植生環境を踏まえ，鳥類相とその変化について検討を加えた。", "subitem_description_type": "Abstract"}]},
