Mainly negative news

Another 2 disappointing visits to the site at Billinge but at least the garden is producing better than expected results.

Billinge 12th September 2018
A total of 31 birds from 3 nests may not sound too bad but it was well below what I have come to expect from this site in mid-September. The big news was the continued lack of Goldcrests, only 1 caught and that was the only one seen or heard, and the low numbers of Chiffchaffs, 2 being a pitiful total for the date. Visible migration was almost none existent and the few Meadow Pipits that were moving were not even passing over at the rate of a trickle, more of an an intermittent drip. The only highlights were a late(ish) Willow Warbler and a similar late(ish) Whitethroat.
Ringing totals (retraps in brackets) were: Blue Tit 8 (1); Great Tit 4; Willow Warbler 1; Chiffchaff 2; Blackcap 2; Whitethroat 1; Goldcrest 1, Song Thrush 1, Robin 1, Meadow Pipit 4, Linnet 2, Goldfinch 2, Reed Bunting 1.

Billinge 13th September 2018
If I thought the 12th was poor the 13th was even worse. Nothing was caught in the first hour and only 9 birds were caught after 3 hours so I cut my losses and packed up early. Goldcrests were absent again which continues to suggest there has been a crash in their population; I have only ringed 3 so far this September compared to 56 by the same date in 2014, 34 in 2015, 58 in 2016, and 90 in 2018. The lower than usual numbers of Chiffchaff also continued. Sightings of note were limited to a high flying Song Thrush that was heading south, a Siskin south and another or the same north later, and a grounded Wheatear.
Ringing totals were: Blue Tit 1; Great Tit 3; Chiffchaff 3; Blackcap 1; Reed Bunting 1.

Garden 1st to 14th September 2018
Back home Starlings are visiting the feeders in bigger numbers and more often than they usually do at this time of year. A total of 53 were ringed from the 1st to the 13th and I manged to ring another 8 on the 14th which is unprecedented for my garden. While I catch large numbers in May and June numbers usually fall off sharply in July and I don't normally catch any in August or September. This year numbers dropped off as usual through most of July but then they started to pick up again towards the end of that month and they have continued to increase since then. Now a mob of up to 30 Starlings visit the feeders periodically throughout the day and more than one mob may be involved.

A retrap Starling caught on the 13th was suffering from avian pox. It had at least 11 lesions of various sizes dotted about its body although most (6) were on its head. It was originally ringed on 20th May when it showed no sign of the disease. A set of images and details will be sent to the Garden Wildlife Health project via their website.
