カバーの説明
本書の表紙に描かれているのはベニハワイミツスイという鳥です。'i'iwi（イーヴィ）またはscarlet Hawaiian honeycreeperとも呼ばれます。学校の宿題でベニハワイミツスイについて調べていた著者の娘さんが、本書の表紙にこの鳥を選んでくれました。アトリ科に属する多くの種は絶滅あるいは絶滅危惧種ですが、ベニハワイミツスイはハワイ諸島原産の陸鳥の中で3番目に多く生息しています。この色鮮やかな小鳥はハワイのシンボルであり、ハワイ島・マウイ島・カウアイ島に大きな生息地が見られます。
成鳥の体は深紅色で、黒い翼と尾そして長く湾曲したくちばしを備えています。草木の緑色と対照的なので、容易に発見できます。その羽はハワイの貴族たちがマントやヘルメットを飾るのに多用されていましたが、近縁種のキゴシクロハワイミツスイ（Hawaiian mamo）のほうが神聖だとされていたため絶滅を免れました。
ベニハワイミツスイの主食は花の蜜やオヒアレフアの木ですが、小さな昆虫を捕食することもあります。毎年の花の開花に合わせて、低地から高地へと移動してゆきます。別の島へと移動することもありますが、自然破壊のためにオアフ島やモロカイ島でベニハワイミツスイを目にするのはまれです。ラナイ島では1929年に絶滅しました。
ベニハワイミツスイを保護するための活動が行われています。鶏痘や鳥インフルエンザなどに感染しやすく、森林破壊や外来植物の繁殖の影響も受けています。野生の豚が作った泥浴び場が蚊の住みかになるため、豚を森から遠ざけることによって蚊が由来の病気を防ごうという活動もあります。外来植物を駆除して森林を復活させ、ベニハワイミツスイが好む花を繁殖させようというプロジェクトも進行中です。 ...
