Sunday 30th June 2019

June started with a dip. On the last evening of May somebody who lives at Le Bigard posted a recording on Facebook of a calling Nightjar and so a few of us went down the next evening and lurked in the gloom. It was a bit of a long shot as it wasn’t exactly good Nightjar habitat and so the bird was just likely to be passing through. We heard nothing.

Looking at the database it seems that I recorded zero bird sightings in June, a very poor show. However, I did get the moth trap out every weekend and the highlight was a new species for the garden and my second ever Bright Wave on 28th June. Quite a rare visitor to Guernsey although I have had one before, flushed in the daytime at Rousse, so it may breed here locally. Even if so, it is likely a recent colonist. That night was a good night in general and there were 57 Large Yellow Underwings which is very unusual for my garden. I also had 3 Dioryctria abietella (probably a migrant here) plus a few others I rarely get - Light Arches, 2 Mottled Beauty, Lathronympha strigana, Caloptilia elongella.

I’d also had a new species for the garden on 1st, the tortrix Lobesia reliquana which I’ve seen before in the wooded valleys. Other notable moths were a Little Thorn on 1st and a Marbled White Spot on 14th.

The other interesting thing that I found was a plant growing by the road at Port Grat. I had driven past it a few times and couldn’t be sure what it was, so I stopped one day on the way home from work. I discovered it was a rather beautiful iris, of a species I didn’t recognise. It had pure white petals and a deep golden yellow centre to the lower lip. I liked the sound of “Fried Egg Iris”. It wasn’t in my flower book, but some research online revealed it to be Turkish Iris (Iris orientalis). Not a native species of course but it is growing in a wild area amongst other coastal grassland species. This doesn’t seem to have been recorded “in the wild” in Guernsey before and not very often in the UK either.

I didn’t really see much else different this month. June is often quiet for me as my hay fever restricts my time in the field. But here are a selection of photos from the month.

Pine Hawk-moth - garden, 1 Jun 19 - with the larger moths the camera on the phone is good enough nowadays and much more convenient for a quick snap.

Lauritrioza alacris or ‘Bay Sucker’ - garden, 2 Jun 19 - I noticed interesting galls on one of the shrubs in the garden and looking closely found loads of these distinctive creatures seemingly dancing.

Procumbent Yellow Sorrel - garden, 1 Jun 19 - I’ve been selective about which ‘weeds’ I have been removing from the shingle, this species seems to like the conditions and grows well.

Knotted Hedge-parsley - 6 Jun 19 - this species isn’t uncommon on certain parts of the coast and has these tiny flowers up against the stem. It is an umbellifer but doesn’t look like one.

Scaeva pyrasti - Port Grat, 11 Jun 19 - hoverflies can be difficult to ID from photos, so for these species the proviso is that they may actually be a similar-looking species than the label says.

Friday 31st May 2019

The second half of May can sometimes produce something outstanding but, more often than not, it is quiet. There were no rarities to go twitch and I didn’t find anything notable either. So spring just petered out. I went for a walk round Pleinmont on 19th May and managed to get there at first light which is something of a novelty for me these days. In the Societe fields two different Sedge Warblers were singing away and a single Whinchat was perched up. That was more or less the sum total of migrants though and so the highlight of the morning was bumping into the male and female Cirl Buntings feeding on the turf by the clifftop, just west of the BBC field. They have been very elusive for the month or so they have been present and my snap below is apparently the first pic of both birds together!

On the way back I stopped off at L’Eree and saw the rarest bird of the day, a fine (!) Canada Goose nibbling the grass on the Aerodrome, with a Brent Goose for company. Records of this species in Guernsey are still in single figures. After coming back down from the goose-high, I popped in to the hide at the Claire Mare where the wintering Spoonbill had now been joined by a second bird, both of which were typically asleep.

The most atypical sighting during this period was the pair of Fulmars that I drove past on the way to work at Albecq on 21st. Every now and then I see a distant Fulmar offshore from the patch but these two were gliding along the rocky coastline right alongside the road. I spotted them as they were passing the Guet and then they carried on west, skirting the headland then into Albecq Bay, over the road to Fort Hommet then back out to sea when they reached Vazon.

On 28th May I had a nice walk down to the mooring at Le Gouffre, somewhere I had never been to before, and took lots of photos. A new plant was Wood Spurge which was so obvious that I was surprised that I hadn’t recorded it before. A Hairy Yellow-face Bee was a new species also and if you look closely at the photo, you can see that it has a little hitchhiker! This is something I have never seen before - the larva of an Oil Beetle. These little larvae wait around on flowers and grip themselves onto any passing bee that lands. They then ‘ride’ the bee back to its nest where they jump off and continue their development in the bee’s nest. Fascinating stuff.
