Garden Birds: Slimbridge WWT sightings- Humbug's back

After a few days in France I arrived back at home at 2am in the morning and started checking any interesting sightings which I may have missed due to Britain faced with remnants of a hurricane from the America.

My Slimbridge Sightings

30+ teal
100+ wigeon
10+ pintail
20+ pochard
20 white fronted geese
50+ Feral banacle geese
A few migrant chaffinches (all females)
10+ probable migrant great tits
5 cormorants
A mistle thrush
100+ lapwing
10+ curlew
A buzzard
1 POCHARD+ FERRUGINOUS DUCK hybrid
8 COMMON CRANES- 7 from the GCP (Great Crane Project and the wild individual)
1 BEWICK SWAN- Humbug has arrived, yet again, first to Slimbridge this year. 2 bewicks arrived firstly at Blagdon Lake and 7 landed on Northwick Warth as they had overshot Slimbridge. The 7 stayed at the warth for less than an hour before flying to Chew Valley Lake where they stayed for a few days. After, they flew to Slimbridge on the 27th but have disappeared leaving Humbug. Where have they gone? They may come to roost at Slimbridge but I haven't seen any reports of them around. Humbug is special as she has been the first Bewick Swan to arrive back at Slimbridge for three years now and luckily for me I saw her today and last year. In fact, she was the first Bewick swan to arrive in Britain last year.
