Po
třech týdnech sledování máme z 19 budek pro sýkorky rozestavěno
14 hnízd. Z toho 3 jsou hotová a čekáme na první vejce. Jen do
jedné budky se žádný pták nepodíval. Některá hnízda sýkorky
postavily během jednoho týdne a některá se staví pomalu, že by
rozdíl mezi koňadrami a modřinkami?
After
three weeks of monitoring nest boxes we have 14 from 19 nests in
progress. Three are already built and we are waiting for the first
eggs!. There is only one empty nest box, which haven´t been visited
by a bird. Some of nests were built in one week and some of them are
built slowly. Should it be the difference between big tits and blue
tits?

| Progress of our nests after tree observations. Small dots is poo from birds, who have slept in boxes. Black filled boxes are in progress from 1/4 to 4/4. And NL means, that nest is lined by hair and prepared for eggs. |
