Peregrines 2014

Connemara must be one of, if not the only place in Ireland where breeding Peregrines are scarcer than breeding Merlin. Of the eight Peregrine sites that I checked this year (two of which were new sites), I only confirmed breeding at only one site.
Only three of eight are found inland in the uplands while the rest are found on coastal and island cliffs.
There are references to "aierys/ayries of hawks" in two locations in Connemara from as far back as 1626 AD in O'Flaherty's hÍar Connaught. These were undoubtedly Peregrines given the locations in question. Chicks were taken from the nest "for field-sport (falconry) and were held in high-esteem".
Recent years have seen a significant increase in numbers of breeding Peregrines in stone quarries and even to a lesser effect on old castles and tower-houses in the rest of the country. The same increase hasn't been as noted in West Galway unfortunately. A few pairs try to breed in the Twelve Bens and Maumturk Mountains each Spring but it usually isn't long before they realise that there is a complete absence of any prey bigger than a Wheatear. It's impossible to raise a brood of chicks on this. This all again relates back to the denuded landscape of the uplands as a result overgrazing by sheep.

Irene O'Brien a colleague of mine has undertaken a colour ringing scheme for Peregrines for Galway, Mayo and Sligo for the last two or three years. As part of this we colour ringed the two chicks in the one successful nest here this year. I forgot how big Peregrine chicks are in the hand as I usually only see Kestrel and Merlin chicks out here. It was an nice long abseil down the chicks and my first abseil into a Peregrine nest. They are using an old Raven nest. The only successful Peregrines last year used another old Raven nest but the Ravens as they moved back into that location this year.
The colour ringing project has already provided some interesting recoveries. One Peregrine ringed by Irene only last year in the Ox Mountains up in County Sligo turned up here near Ballyconneely this winter. It unfortunately had at least one broken wing (possible car casualty) but the bird has thankfully recovered but not good enough to be released back into the wild. It now resides in the Burren Bird of Prey Centre in County Clare.
As I mentioned with the Kestrels, Peregrines had a very poor breeding season this year, most likely the worst in recent years. I think Peregrines may have been worse hit in the West as they seem to have fared reasonably well in the East where a similar ringing project is also being undertaken.

Giving out as usual!

Note the corvid wings on the bottom left. I came across the remains of Jackdaw, Common Gull and Whimbrel in the vicinity of the nest. There's a nearby breeding pair of Chough, I wonder if these corvid remains are some of the unfortunate fledged Chough chicks...

Chough, Small Blues & Machair

Some shots from my Bumblebee Survey transect at Aillebrack last Sunday. Nice to see a few Small Blues out on the commonage. This small area is the only location that I know of where the species occurs in Connemara. A few hoverflies around also. I don't have my hoverfly book to hand so I'll have to add names to a few later. The meadows and machair commonages are looking fantastic at the moment. The commonage here is grazed only by a small herd of cattle. The difference between this and sheep only commonage is stark. Sheep are generally bad news for most habitats in the West of Ireland.

Kestrels 2014

We're all finished up with the raptor ringing season as of last Friday 20th June. It's been a generally poor year all round for birds of prey species here in West Galway.

The pairs that were successful produced good clutch sizes and fledged chicks in good numbers so it doesn't look like food was an issue. However of the 19 sites that I checked here;
  • eight were outright failures/didn't attempt breeding at the locations,
  • two contained predated eggs (Hooded Crows & large gull mostly likely predators) and
  • nine managed to successfully fledge chicks.
The most likely culprit for the poor breeding season was possibly the extremely heavy rainfall in mid May, I believe Saturday 17th May was particularly bad with one rain downpour that lasted for most of the day. It's not only Kestrels that suffered from this as Peregrines were possibly affected to a greater degree in Connacht.
 
John Lusby of Birdwatch Ireland and I only managed to ring four broods of chicks this year and each brood contained five chicks. We were too early for one brood and too late for another. The winter storms have had an effect on some of the nest sites as the ledges of three pairs have been washed away unfortunately.

Searching for an active nest. Ran out of time but came back a week later and the chicks were on the wing so we would have been too late anyway. These were one of the earliest pairs I've had here.

Bog-trotting June 2014

A few pictures from the Connemara Bog Complex SPA & SAC. I've been spending a fair amount of time out on the bog and this summer between the on-going Golden Plover and Merlin surveys  Some great views of a young Irish Hare leveret who wasn't very put out by my presence on one of the days. Viviparous Lizards are quite common throughout Connemara and are out only native reptile. Also the ground beetle Carabus clatratus which is another species that is restricted to larger areas of untouched blanket bog.

Inishbofin & Inishark May 2014

A few pictures from the adjacent islands of Inishbofin and Inishark from last month. I was giving a talk out on Inishbofin and had some views of one showy Corncrake up at the West end. Light was a little too strong and was at the wrong angle. It's looking there are at least a dozen singing males again on the island and I wouldn't be surprised if there a few more before the official counts are finished. I was out with the Living the Wildlife crew who are filming Great Skuas on Inishark also. Looking forward to seeing the finished product on the telly which will probably be next year. The skuas hadn't hatched up until last week. Numbers appear to be increasing from a very low starting point for the last ten years or more since they established themselves on the West coast of Ireland. I had a surprise of a Turtle Dove with around five Collared Doves as I leaving Inishark. There have been two Corncrakes on Inishark this summer from the nettle patches around the deserted houses. Unfortunately the Corncrakes don't have anywhere else to go on the island as there are no fences on the entire island and sheep have the whole place grazed to the ground, a common issue on a lot of offshore islands in recent summers. Inishark was alive with Wheatears the last day as the first broods of the year had just left the nests. I hope to get out to Inishark again shortly for a longer stay fingers crossed. I've only ever at most spent a few hours on the island before and you always find yourself running around like a headless chicken before you have to leave again. Things have been a little hectic for the last two months between ringing Ravens, Peregrines and Kestrels. We've also into our second year of surveying Golden Plovers on the Connemara Bog Special Protection Area. Merlins are again to the forefront at the moment. They are always later in their pregress compared to the other two falcons. I've found active pairs so far this summer. I'll post a few pictures on all these at some stage.
