ヤマガラの卵

庭に設置したヤマガラの巣箱内に設置したカメラの画像です。今朝7時22分の画像に卵が2個映っていました。昨日の18時29分の画像には卵は映っていませんでした。早朝に産んだものと思われます。普通ヤマガラは1日1個卵を産み、合計で3個から8個産むと言われています。いきなり2個は双子の赤ちゃん？

A picture of the camera which was installed in the birdhouse of a varied tit installed in a garden. 2 eggs were reflected on a picture at 7:22 of this morning. The egg wasn't reflected on a picture at 18:29, yesterday. It seems to have born early in the morning. A varied tit generally lays 1 a day egg, and it's said that 8 bear from 3 in total. Suddenly, are 2 a twin baby?
