チービシでマミジロアジサシ

チービシ(慶伊瀬島)でマミジロアジサシを見てきました。ライファーです。^^

ナガンヌ島などで営巣もしているようで二十数羽の群れの飛翔も見ることができました。想像していたよりかなり大きくオオアジサシほどありました。また、頭から背中にかけての黒とそれ以外の白の部分が美しいコントラストで大変迫力のあるアジサシでした。

鳴き声も聞くことができました。同じ島にいたベニアジサシやエリグロアジサシとは全く異なる鳴き声でした。

Three Bridled Terns appeared all at once. The individual at upper right is dropping a bomb. ^^;

They flew close by. I was surprised at the size of the Bridled Terns — a first for me.

They seemed curious about people, and occasionally came close to check us out.

かなり大きくなったツミのヒナたち

先日、動画でも紹介した攻撃的なツミのペア の子どもたちも大きくなり、1羽は、巣のそばの枝に止まっていた。しかし、両親の攻撃が一段と激しさを増していて全く近寄れない。Google Maps で調べたところ、営巣木から約80メートル離れた地点でオスとメスの攻撃に遭いました。^^;

それ以上は、近づく気にもなれませんでしたのでヒナたちの写真はありません…。^^;

A female Japanese Sparrowhawk charging straight at me at tremendous speed. You can probably tell from the way the wings are pulled in. I think the top speed exceeded 80 km/h. Small birds don't stand a chance when one of these comes after them… ^^;

ガラスヒバァ vs. アオカナヘビ

道端でガラスヒバァとアオカナヘビが戦っていました。アオカナヘビがぐったりしたところでガラスヒバァがアオカナヘビをくわえたまま茂みに入ってしまい、呑み込むところまでは確認できなかった。

The Dinodon semicarinatum had bitten the tail of a Ryukyu Green Lizard, and the Ryukyu Green Lizard had bitten back at the snake's head.

For a moment the Ryukyu Green Lizard managed to escape from the Dinodon semicarinatum's mouth, but with a remarkably swift movement it was bitten again.

Once the Ryukyu Green Lizard went limp, the Dinodon semicarinatum raised its head high and carried the lizard off into the undergrowth.

エリグロアジサシ営巣突入

昨年見つけたエリグロアジサシの営巣地は、ことしも順調に営巣に入りそうです。抱卵に入っているペアもいました。フラッグを装着した個体もいました。昨年も フラッグをつけた個体 を撮影していますが、アルミリングの番号までは読めないので同じ個体かどうかは不明。

It seems both migration and breeding are a little late this year, but there were individuals already incubating.

The individual with a flag on its left leg appeared to be a male, seemingly urging the female to build a nest at this spot.

若ツミのペア産卵間近

きょうは、6月も最後の日。今月は3日間しか休みのない忙しい月でした。毎年、6月はほとんど休めない…。^^; この時期は、野鳥の子育て最盛期なのでもっとフィールドに出たいんだけどねー。

先月見つけて、今月の中ごろから巣作りに入っていたツミの若いペアも間も無くというかやっとというか、そろそろ産卵の兆しが見えてきました。いくつか観察しているツミの営巣で、すでに巣立ったところもあり、ことしはかなりばらつきがありますね。

この場所のツミは、観察している中でずば抜けて人を恐れません。今の所、営巣木の真下でおじさんが車の掃除をしようが、草刈りが入ろうが全く動じる様子はありません。しかし、 先日の他の場所の若いカップル のようにヒナがある程度大きくなったら豹変して人間に攻撃的になる可能性もありますので、今後の動向を引き続き見守ってみます。

A male Japanese Sparrowhawk sitting in the nest. Even when a man opened his car bonnet and started cleaning it right below the nest tree, the birds paid no attention at all, taking turns carrying nesting material and testing the feel of the nest cup.

A female (left) and male Japanese Sparrowhawk. It's rare to get a shot of a pair perched neatly side by side, so this one made me happy. Seeing them together like this really highlights just how small the male is.

Handholding the 600mm f/4 for the first time in a while — it was heavy. ^^;

A similar frame to the one above, but that was shot with the 600mm f/4 and this one with the 100–400mm. The difference in background blur is quite striking.

The male flew in and mounted the female's back directly, attempting to mate, but was rebuffed.
