Wintersett + Tree Sparrows 21.06.18

10 - 15 degrees with sun, scattered cloud and a cool north westerly wind.
Anglers CP: Oystercatcher 2 adults + 1 juvenile.  Herring Gull 2.
Odonata:  A Ruddy Darter was in the CP back field.
Tree Sparrows: After brilliant first broods with no losses and broods of 5 young, 2nd broods are very poor.  Only 30 to 40% of pairs are having a 2nd broods whereas it's usually around 80%..  The reason this is happening is a mystery. All 3 nestbox sites around the area are experiencing the same results.
