After a wet and often frustrating May, June started warm and dry, before wet and cool conditions resumed mid-month. It was, however, a pretty productive month – at least in terms of quality birds. One key aspect at my patch at least was that the aggressive pair of Lapwings nesting on the eastern shore of Wader Pit fledged their chicks and finally calmed down, deciding that chasing every other bird that landed there wasn't worth continuing after spending the entirety of the previous month seeing off any interesting waders. But more on that later.

The opening day of the month produced a fantastic male Montagu's Harrier at the Great Fen, south of Peterborough. With the bird in potential breeding habitat, wardens wanted the news kept off-air in case of a female turned up. But, as it quite unsurprisingly transpired, the promise was short-lived and the bird cleared off after just a day.

The highlight of the month (and likely my birding year, at least locally) was a Caspian Tern at BLGP on 20-21 June. I saw the bird here in 2017, having twitched back from London to connect with it, never thinking I'd ever get it back as a patch tick. Less than four years on and it repeats – and on the very same pit!

The find was most fortuitous in its nature and a classic example of what must be being missed on patches nationwide, even by the most dedicated of watchers, and especially at perceived 'quiet' times of year. The random appearance of various rarities at inland sites during June had encouraged me to keep checking the patch on a daily basis, and a lovely male Ruff on 19th had spurred me on.

Two daytime visits on 20th had produced little and were it not for my girlfriend needing to head back to her house late that evening, I would never have stirred from the sofa. After dropping her at home, it was already 9.55 pm, yet there was just about enough daylight left to give Wader Pit a quick glance. I got there and within a minute or so picked up the tern sat nonchalantly among the hundreds of Black-headed Gulls roosting on the east shore.

By this point it was just after 10 pm and the light fading rapidly, yet Jake Williams and Bob Titman still managed to make it to see the bird before the light was lost. The bird got up and flew around a couple of times, calling, which was absolutely brilliant to hear/see as it passed at close range. The light was far too gone for any sort of proper photos, so it was just a case of appreciating the bird in the little light left before darkness fell.

Next morning, Paul Bolton was already on site around 3.30 am and the tern was still there. Mad, really. Almost 24-hour birding. I arrived a short while before 4 am and the bird was still sat there, on Wader Pit, looking pretty chilled out, despite most of the Black-headed Gulls having already departed. But then it got up around 4.20 am, just as the light was beginning to improve, flew around, called a couple of times and headed off south-west, never to be seen again. In all the views we'd had, we couldn't be sure if the bird had a ring or not, thus weren't able to confirm if it was one of two birds commuting between East Yorkshire and north Lincolnshire sites, nor a yellow-ringed bird which turned up at Llanelli WWT a few days later. Interestingly, the last BLGP bird, in 2017, was also seen at Llanelli! Funny how these things work.

Well, that was a tough May. The cold conditions dominated right up until the final days of the month, and there was so much rain!

Despite the difficulties, there were a few obvious silver linings which helped my local year list reach 187 by the end of the month. Given that the Peterborough area was something of a forcefield for deterring quality birds throughout the month, and with neighbouring counties scoring multiple Temminck's Stints, Red-necked Phalaropes, Golden Orioles and the like, this is a pleasingly high total – largely thanks to the brilliant spell we had back during the cold weather in February. The only issue is that there aren't any easy species left now, and the lack of bonus birds in May might be telling in the quest for the elusive 200 mark (a feat never achieved in the area).

One of just three additions to my local year list during the period from 11-31 May was European Turtle Dove. This ever-scarcer species is just about clinging on in the Peterborough area, largely due to a resilient (yet still perilously small) population clinging on in the Etton-Maxey area, thanks to habitat creation and supplementary feeding (shout out to Langdyke Trust for their role in this). This is presumably the source of other, satellite territories in the Deepings area: I had three singing males at two sites away from Etton-Maxey in the month. At one of these, which has particularly nice TD habitat, I started supplementary feeding as soon as I clocked the birds were back. Hopefully it helps them out.

Spotted Flycatcher is another bird that has declined dramatically – especially in the east of England. It was never particularly numerous in the Peterborough area, at least in my time birding, but it too seems to be largely gone from here, with many of the sites that had birds when I started out 20 years ago now flycatcher-less. It was good to see a pair back at Southey Wood on 20th, after Paul Bolton had picked them up there the previous day – this site now appears the only regular publicised spot for them in our area.

The third addition was another 'Spotted' bird, this time a crake. This species is an annual summer visitor to the Peterborough area, although some years are better than others for them. As far as I know, this singing bird is the only individual heard in the area so far this spring.

While some of the aforementioned species become ever trickier to find locally, one species that is doing well is Bittern. Six nests were found local to me this year, with birds booming at several sites and the likelihood being that there are even more breeding pairs than these figures suggest. Despite the weather, with so much cold and rain, all six nests did well and fledged young. It's a bird really on the up and further habitat creation through the regeneration of former gravel pits will no doubt continue to see it do well. I was thrilled to be involved in monitoring of these birds and was able to assist in ringing one nest (under licence). Amazing things!

Meanwhile, I have been doing survey work on a site in North Wales on a monthly basis. Despite the continuing cold and wet weather, it was nice to enjoy Pied Flycatchers, Common Redstarts and the like on territory. Hearing these species singing – and indeed seeing them in their spring finery – is an experience that passes me by in most years, so it's been a welcome treat to get reacquainted with them. They were upstaged by Wood Warbler in the Clwydian Range not far from my dad's, which was a nice surprise, showing brilliantly and singing at eye level in an area of regenerating birch forest.
