Swifts log 2022
Sun 1 May, nestbox #4: Arrived this morning, almost certainly one of our original pair who have been back every year since we opened the boxes in 2016. Let’s hope that their partner also returns soon so that they may repeat their past breeding successes: 3 chicks in 2021, 1 in 2020, 2 in 2019, 3 in 2018, 3 in 2017.
Mon 9 May: A second swift arrived this evening, roosting in #2.
Tue 10 May: A big day! A partner has joined the lone swift that has been roosting in #4 for 9 days. A pair has arrived into #3, and a single swift into #1. Five swifts seen flying over Mannings Close this evening. All boxes now occupied – six birds in all, including the single in #2, roosting again tonight.
Thu 12 May: A partner for #1 arrived early this morning.
Fri 13 May: A partner for #2 arrived today, completing our colony of four breeding pairs. On past form we may expect eggs in about two weeks time. Watched about a dozen swifts in the sky this evening.
Thu 19 May: Rather sooner than I expected: one egg in each of #3 and #4.
Sat 21 May: One egg in #1, two eggs in each of #3 and #4. None in #2.
Mon 23 May: A second egg in #1, a first in #2 and a third in #3. Total now 2 + 1 + 3 +2 = 8.
Wed 25 May: The old-timers (our original pair) in #4 have been so diligent in incubating their eggs, and so skilled in swapping the duty, that I have been unable to see into the nest since Sunday, but there has been no change in the numbers of eggs in the other boxes.
