1 June - What a miserable start to the summer month of June - low cloud, drizzle and only a brighter period around the middle of the day which boosted the temperature to a high of 14C for a short time.

The conditions certainly had an effect on the Swifts in SW(LE) as they left the eggs unattended for one period of just under half an hour just after noon.

Here are the day's timings -

WS in 12.36pm (with feather) ; S2 in 3.56pm  -  WS out 3.59pm

2 June - If yesterday was miserable, today couldn't have been more different, with bright, mainly blue skies, a slight breeze and feeling much warmer than the official 21C registered at Farnborough.

First, the day's timings -

SW(LE) -

WS out 4.53am

WS in 4.55am   -   S2 out 7.33am

S1 out 7.14am

S1 in 9.42am    -   S2 out 9.45am

S2 in 11.35am    -   S1 out 11.37am

S1 in 3.54pm    -   S2 out 3.59pm

S2 in 6.09pm    -   S1 out 6.10pm

S1 in 8.36pm    -   S2 out 8.41pm ; S1 out 9.11pm (eggs left unattended)

S1? in 9.15pm ; S2? in 9.36pm

At last, both pairs seem to have followed a fairly similar pattern of incubation today which included the eggs being left unattended for a short period this evening, 8 minutes in SW(LE) and just 4 minutes in SW(UP).

Sometimes when a bird returns to the box it brings something, usually a feather, to add to the nest. This afternoon the pair in SW(LE) seemed to prefer plant materials.

When White Spot arrived at 2.31pm she had a small piece of what appears to be a fern frond in her beak,

and when it partner returned at 4.17pm it brought in what looks even more like a fern frond, as well as a small feather.

While my monitoring of the Swifts will continue, family commitments mean that there will be no further diary entries for the time being. I continue to record activity in the nests, and the webcam will continue.

When I am able to restart the diary I intend to 'catch up' in some detail, especially regarding the development of the chicks that hatch. The eggs in SW(UP) should hatch around 9 June, while those in SW(LE) are due around four days later, around 13 June.
