Excellent stuff Open your eyes! Helping protect probably the most important sea bird colony in Ireland. A great honour. I was on the island two years ago for a day, a great experience. keep us updated on the terns progress through the season. With your enthusiasm for wildlife you will do a great job.

Thanks guys! We'll have some internet, so we hope to do a blog about it throughout the season - and I'll hopefully have some extra pictures and updates to share here too!

Rare bumblebee rediscovered after 88 years

A rare bumblebee species not sighted since 1926 has been recorded in a park in Rathfarnham, Dublin. Eddie Hill, a gardener at St. Enda’s Park and avid bumblebee recorder for the National Bumblebee Monitoring Scheme, spotted the unusual looking bees feeding on flowers last week within the grounds of the park. Having sent photographs and sent two specimens to the National Biodiversity Data Centre, ecologists Dr. Tomás Murray and Dr. Úna Fitzpatrick confirmed that it was the rare Southern cuckoo bumblebee, a species not recorded in Ireland for 88 years.

Fair play to that man for spotting the cuckoo bees.
They have an interesting life cycle

Like other cuckoo bees, it’s unusual in the sense that it doesn’t make its own nest, but invades a host bee’s nest, kills the queen, then uses the host workforce to rear its young.

I wonder does that mean that the host colony would run out of workers, and then collapse, around the time the young cuckoo bees move on to somewhere else?

Three pairs of Golden Eagles bred in Donegal this year

The Glenveagh Golden Eagle Pair incubated their eggs for four weeks before abandoning their nest due to 36 hours of very heavy rain in mid April.

Our other experienced pair have a single male chick, which was ringed last week - see abseiling photo and chick photo below. Thanks to the Gartan Outdoor Centre for setting up the rigging for my abseil and to Johnny for all his support.

A new inexperienced pair bred for the first time this year. They sat the full incubation period but they failed to hatch.

However, it was fantastic to know that the young female was an Irish wild bred chick - reared by reintroduced birds in Glenveagh in 2010. This is the first time an Irish bred eagle has bred here since our projects began.

The nest itself was by far the biggest nest we have seen since 2005, when the eagles started nesting again. Unfortunately, the position of the nest was quite exposed, maybe due to inexperience.

As scavengers and opportunists they're attracted to the city by the filth that's thrown around by humans.Maybe he needs to address the filth problem first before persecuting the birds!

tricky D

If you live in an area with plenty of gulls, you'll realise it's not funny at all with the incessant noise at almost all hours and aerial attacks.

And Bonedigger is right, they're mainly around to scavenge our filth.

recedite

If they are attacted to filth, that must be why the FF politician is plagued with them. WTF is a Dump Gull anyway? Is this some kind of vagrant species?

i know there was a project run out of trinity to study the effect of excluding deer, but it seems to have been a different one, as the article above mentions seven exclosures, but the one i was aware of had about 24; and i think it came to the opposite conclusion, but i don't have a link handy to confirm whether this was the case.

recedite

As a basic principle, if you were mass planting broadleaf seedlings on clear-felled ground, it would be better to exclude deer until the growing tips were well out of their reach.
If planting only a few in an established forest, individual guards on the trees would be better.
They are saying that its good to have deer browsing the undergrowth under biggish trees.

Shouldn't we exterminate them for not being native? :P

There is a huge difference between a species naturally expanding it's range, or altering it's range due to environmental conditions, and the accidental or deliberate introduction of an alien species.

Apart from the fact that the animal gets there on it's own steam, I do not see a whole lot of difference. Ultimately it seems to boil down to whether or not we like the change.

There's a huge debate on that which would drag us off topic, but suffice to say you are wrong in your assertion that it's down to how we respond to the change. Most of our native wildlife found their own way here - birds being the obvious example - would you eradicate them? Natural colonisation is accepted but not introductions for a very good reason.

recedite

Suffice it to say that there are animals considered native but introduced, such as rabbits. Native but exterminated, such as wolves. Even birds can be introduced and then naturalise.
We often make some effort to protect or exterminate such species, as it suits at the time.

"Naturalized" does not mean "native" - a species can only be classed as native if it arrives under its own steam without any human assistance. Obviously some introductions are less damaging than others but it still doesn't make the likes of rabbits, parrots etc. native to these islands

Magpies made their way to Ireland under their own steam but few would consider them native, even though they have been here for hundreds of years.

They are native and most people would consider them as such.

There is talk in the UK about eradicating the rose necked parakeets.

Most of our native wildlife found their own way here - birds being the obvious example - would you eradicate them? Natural colonisation is accepted but not introductions for a very good reason.

The way we differentiate between what we consider introduction and what we consider colonization is more or less arbitrary, however. Nor do we really use the introduction part as the criterium. No-one minds eagles being unnaturally re-introduced, for instance: we have decided that they are "native" or that their extinction was "unnatural". We see them as a valued addition to the natural systems that we introduce them to.

However, when it comes to wild boar, which share with eagles the distinction of once having been part of the irish eco-system and which in all probability were wiped out by us humans, then we decide that they are invasive because they change certain biological systems, and because their re-introduction was either accidental or purposeful but not done with our general approval.

The only difference between these two examples seems to be that we like the eagles and like the changes they bring to our eco-system, but that we do not like the changes wild boar bring with them.

Another example are the new, bigger shrews which seem to be colonizing Ireland. We did not plan it and we worry about the changes it will bring, and if they will out-compete other species, even possibly driving them into extinction.

But we don't know what bee-eaters will do either - what if they thrive and put more pressure on the already suffering honey-bee?

In the end, we simply like bee eaters, and we have a tendency to consider things that happen without human intervention as somehow better because it is "natural" - a rather arcane term, the way we tend to use it.

We could also make the point that there is a very low likelihood of them reaching the kind of population densities that would seriously impact other wildlife.

But we should not pretend that the fact that we choose not to counteract the appearance of certain species while we do stop other species has anything at all to do with some arcane quality called "naturalness" or "nativeness".

"Talk" yes. That is exactly the point. On the one hand, they attack fruit crops, but on the other hand many people in built-up areas like to see them around. So the jury is still out for them. Ultimately it seems to boil down to whether or not we like the change.

If they are judged to have a negative impact on native wildlife, they should be removed. Whether people like them or not is irrelevant.

Vivisectus

then we better kill off the bee-eaters. They could very well put extra pressure on the native bees. Besides, if it wasn't for human-created unnatural climate change they may not have gotten here, so it sort of counts as an introduction.

Are (European) Bee eaters responsible for any decline in bees in Europe? no there not.

There are no Bee-eaters breeding in Ireland, the few vagrant we get are over-shoot migrants.

Ah, but that is because they are native there no doubt. We have no data on what happens when they are introduced.
