29th - 30th July

A Greenshank and 7 Whimbrels were among the waders on the 29th. There were no new migrants to report from the 30th, but the long-staying Western Bonelli's Warbler was seen once again at Holland House.

27th - 28th July

A Crossbill was the bird of the day on the 27th, when a couple each of Swift and Sand Martin were the only other sightings of any note.

With the gears of landbird migration still struggling to reengage in autumn mode, a timely jump-start in the fantastic form of a Nightjar was a most welcome surprise on the 28th and easily one of July's highlights. Originally flushed from near the observatory, it soon flew into one of the mist nets and provided a rare opportunity to see one of these bizarre nocturnal goatsuckers at close quarters and in broad daylight.

The year's first Hobby a Kestrel and a Hen Harrier were all new raptors in the afternoon, and a Sedge Warbler ringed at the observatory was either an early autumn migrant or dispersing progeny of one of the island's breeding pairs. Plenty of waders were still to be seen gathered in the freshly cut fields, with 6 Whimbrels among the more numerous species.

Nightjar: the scientific name Caprimulgus and the colloquial name goatsucker both stem from the curious belief that these birds use their spectacularly wide mouths to suckle milk directly from the teats of goats during the night. The island has only recently acquired some goats, so we will be keeping a keen eye out for any suspicious nightjar activity in their vicinity.

25th - 26th July

The year's first Greenshank finally appeared on the 25th, as counts of other waders included 461 Sanderlings, 390 Turnstones and 77 Ringed Plovers. The Dunlin influx, however, was a short-lived event: most of the birds from the previous day had departed to leave just 68 by morning. The only other species of interest were a couple of Swifts and a flock of 16 Lesser Black-backed Gulls. A Leach's Petrel and 51 Storm Petrels were caught that night, while a second Leach's Petrel was seen to be attracted to the tape.

The highlights of seawatching on the 26th were 2 Sooty Shearwaters, 5 Manx Shearwaters and 5 Storm Petrels; a Sand Martin was the day's only other noteworthy sighting.

22nd - 24th July

Seawatching on the 23rd produced the first 2 Sooty Shearwaters of the year, along with 6 Manx Shearwaters. As waders continued to pass through, a Black-tailed Godwit on the 23rd was followed by a flock of 11 the next day, a mass arrival of Sanderlings numbered more than 400 birds, and an invasion 215 Dunlins took place during the day on the 24th. After a lengthy period of inactivity, there were finally some landbirds to talk about on the 24th: a Crossbill flew south in the afternoon, a Swift and a Collared Dove were both new and, unbelievably, stunningly, the Western Bonelli's Warbler reappeared Lazarus-like in the Holland House gardens after more than three weeks of presumed absence!

20th - 21st July

Compensating for a lack of noteworthy avian sightings, the year's first Basking Shark, seen among a flock of feeding terns Kittiwakes and Gannets off Nouster Bay, was a nice find on the evening of the 20th. After dark, another session of tape-luring petrels resulted in 15 Storm Petrels and 2 Leach's Petrels being ringed at the observatory.

17th - 19th July

There was little migration to talk about from three more days of typical midsummer intermission. The flock of Golden Plovers swelled to 629 birds on the 17th, including one highly distinctive leucistic individual. A Short-eared Owl on the 18th was the first for a few weeks, and the highlights of the 19th were a couple of Whimbrels and a flock of 120 Kittiwakes on the west coast.

 Ringing activity in the summer usually focusses on Storm Petrels and the island's breeding birds. A small number of Arctic Terns have now fledged, but a search for Black Guillemot chicks among the boulders at Twingness drew a worrying blank, indicating another terrible breeding season for the species. The Ringed Plovers seem to be having better success, and a few of their endearingly cryptic chicks (pictured) have been ringed so far.

14th - 16th July

The very quiet period continuing, passage of anything other than the common waders was exiguous at best, although such dry spells are to be expected in mid-summer. A Redpoll was flying around on the 14th and 15th, a Heron was probably a new arrival on the 16th and 4 Swifts were seen on the latter date.

Several separate Arctic Tern colonies were established in the spring, but most of them failed completely last month. One colony does now contain a few chicks, making 2012 at least a small improvement on last year's complete wash-out. Flocks of terns remain scattered around the island, mostly comprised of failed adults and non-breeding first-summer birds like this one.
