A sunny morning with temperatures finally feeling like summer, highlight of the morning was the sighting of a male Western Subalpine Warbler, briefly in front of the observatory, but not seen again as of 14:15. Small number of other migrants in the compound; including Chiffchaff, Reed Warbler and a Garden Warbler ringed on monday this week. A Jackdaw briefly landed on our Motus tower, a somewhat unusual visitor to the point, although common in the town of Felixstowe.

Herring Gull (Larus argentatus) out on the beach. 

A bleak morning with strong S winds and rain, leading to ringing being abandoned. A male Wheatear was present on the peninsula following an absence of any Wheatear for 11 days. Multiple Chiffchaff singing in the compound.

Few new migrants in today with 3 Reed Warbler, 2 Chiffchaff & a Mipit plus southbound 25 Swallow & a House Martin. An independent young Wren may well be from a brood in the cottage garden seen a few days ago that are now wandering.

Coronet was first noted here in 2004 & has become annual from 2016 onwards. Formerly on Elms it has, apparently, shifted its foodplant to Privet.

Ringing: 1 Chiffchaff, 1 Reed Warbler, 1 Wren

Saturday 16th May 2026

 

Three baby Great Tits first seen last Saturday are doing well still being fed by mum & Dad which they tend to do for the first couple of weeks out of the nest before they have to fend for themselves.

A slightly warmer morning with at least 6 Reed Warbler chuntering away. At least 22 Swallow, Sand Martin & a Yellow Wag flew south. A Cuckoo flew out of the Customs' House grounds over the caravan site. More baby Starling's are out & about which seems slightly earlier than recent years. Of interest a Whitethroat ringed last year at the end of June has returned.

Sea-watching almost non-existent with a Med Gull the only thing worth mentioning. 

Broad-bodied Chaser's are starting to emerge into the sunshine.

Oak-tree Pug is one of those pugs that can be confused with similar congerers.

Moth trapping: 24 Species present, with 3 new species for this spring, Cinnabar, Vines Rustic and Pale Mottled Willow. 

Bird ringing: 2 Reed Warbler, 1 Blackcap, 1 Dunnock, 1 Willow Warbler
