June 2023

Bird Sightings
In comparison to last June, this June  was warmer. The mean temperature was two degrees higher than last June. May had finished with ten dry days. In June the dry spell continued for another sixteen days giving a prolonged, warm, settled spell. Conditions were generally good for birds trying to get on with breeding with warblers, pipits, chats and hirundines all doing well.

Some observers reported gardens full of young birds. There were many reports of fledged birds in gardens including unfamiliar looking young birds, like Goldfinch without the red face of the adult birds, and Robin with spots and no red breast. Among the familiar garden birds Blackbird, Song Thrush, Chaffinch, Blue Tit, Great Tit and Dunnock seemed to be doing well. Most prolific of all seemed to be House Sparrow, with forty in Shannochie on 30th being one of the larger numbers. Also, there were many reports of numbers of Siskin and Goldfinch with young around, including twenty Goldfinch in Kildonan on 5th and twenty Siskin in Cordon on 29th. Again, it was encouraging to get reports of young Bullfinch, young Greenfinch and young Great Spotted Woodpecker from widespread locations. Twenty Long-tailed Tit including young, in a garden in Pirnmill on 11th was a particular garden highlight.

Away from gardens there were many signs of breeding including, a pair of Mute Swan with seven young at Corrie on 3rd, over one hundred occupied nests of Sand Martin in Glen Catacol on 7th, a family of Linnet at Kilpatrick Point also on 7th, a creche with three female Eider and fifteen young at Ports Buidhe on 8th, a family of Great Spotted Woodpecker in Merkland wood on 10th, a family of Treecreeper in Stronach Wood on 15th, a female Red-breasted Merganser with nine young in Loch Ranza on 17th, a family of Common Sandpiper in Sannox on 26th, a flock of thirty Starling including young in Strathwillan also on 26th, breeding activity of Black Guillemot around the King’s Cave on 29th and a reeling Grasshopper Warbler by Kilmory Church on 30th. Cuckoo, whose decreasing numbers are a cause for concern nationally, seems to be thriving on Arran.

The breeding success of some raptors is linked to the vole cycle. Bumper years of voles tend to be followed by a crash followed by a gradual build up followed by a bumper year in a roughly four-year cycle. 2021 was a crash year with few voles around. Last year and this year the vole population is on the increase and those licensed to monitor Barn Owl and Short-eared Owl territories report a better breeding season than last year.

In June a number of scarce summer visitors were reported: a Puffin in Brodick Bay on 2nd, an Osprey in High Kildonan on 3rd, two Swift in Sliddery on 11th, a Quail also in Sliddery on 18th and a Ring Ouzel in Gleann Easan Biorach on 29th. In addition, there was a report of Storm Petrel on 17th, the first report in ten years. This will feature in a future “Banner” bird note.

Other highlights in a month with over one hundred species reported, included twenty-five Gannet fishing in Brodick Bay on 2nd, the summering Whooper Swan in Corrie on 3rd, four Dunlin on Silver Sands also on 3rd, three Common Crossbill in Glenkiln also on 3rd, thirty-three Barnacle Geese flying over Pirnmill on 6th, a White-tailed Eagle off Dougarie on 14th and a Magpie in Porta Leacach on 22nd. Interestingly there was a report six weeks previously of this vagrant species in the same location.

There were no June reports of Kingfisher and none of Little Egret. It is anticipated that later in the summer both species will be reported dispersing after breeding elsewhere. Also in July, look out for early signs of breeding being over for other birds this year. These could include the return of some Arctic breeding species to our shores, as they travel south. Already in June there were reports of four Sanderling in Blackwaterfoot on 24th and four Turnstone also in Blackwaterfoot on 27th.

Finally remember July is the time when many birds, having raised their young, go about the process of renewing their feathers by moulting them. As birds are vulnerable when they are shedding flight feathers, they literally make themselves scarce. On any walk you may see fewer birds, but they are still around.
