Dear All
I have introduced this as a new topic, because, from my visit yesterday, the rookeries seem to be thriving. The smaller of the groupings has now grown from 14 to 20, and the larger groups are showing a considerable increase in the size of the actual nests, some approaching 1 metre in depth in my estimation.
There is still a considerable amount of activity, to my mind a sign that the rooks have not actually started laying yet, as activity tends to lessen when one of the parents is sitting. The separate rookery at Villadangos, is also thriving, and no more tree removal is evident. There are still no leaves on the trees, and so the birds can be viewed with ease, the large grouping being very spectacular
Regards
Dave

Greetings Dave,
Nice idea to change from the Rooks in danger thread. Good luck!
Look forward to hearing about Rooks breeding.

Dear All
the rooks are doing nicely, things are a lot quieter now, I guess some of them are settling down on their nests, still no leaves so everything still very visible, it is still delightful to sit under the colony and watch the activity.
regards
Dave

Dear All
just a quick update. I took my Mum from E*****d, to visit the rooks today. Lots of leaves on the trees so the nests are not so visible, but still lots of activity, and so far no more destruction of habitat. last week I found a new colony, only visible from the distance, but I will be exploring the area in the next few days. This new colony is some miles/ Km from the other concentration as it is on the Leon to  Benavente road, will keep everyone posted.
Regards
Dave

Hi Everybody
At last an update on the Rooks at San Martin del Camino, Leon and Villadangos del Paramo.

I am quite surprised how few nests are actually left at San Martin, with just 59 nests covering the 5 groups of trees, as compared with 236 previously, agreed we have had some high winds recently, but lack of activity in the area of the rookery, is causing me some concern, especially when compared with Villadangos del Paramo, where 22 out of the 45 nests appear to have survived, and today the rookery was alive with activity, and very noisy, still i will keep an eye on both sites to see what transpires. One positive note is that no more tree felling has taken place, and at Villadangos, no one seems to have removed the fallen trees. I am still not sure how to estimate the number of fledglings that the sites have generated, although a birding friend of mine in the LOG suggested around 2.3 per nest, so even at a conservative estimate of 2 chicks per nest out of the nest count of December, would give us some 140 new birds, although I suspect it could be higher, perhaps Peter at SEO Ronda could give me a clue how to estimate from number of nests.
The map is an update of last March, I hope to add to it at regular intervals until the leaves come back on the trees.
Regards
Dave

Hi Dave,

Thanks for the update and excellent map...

It does seem a bit worrying as to the lack of nests. The reduction is huge...Was there no sign of nest on the ground from being blown out of the trees by high winds or do they just disintegrate and blow away in pieces?

I hadn't realised that rooks used their rookeries in winter. Is that normal?

There are no rooks hereabouts (nor any trees suitable for a rookery; only date palms and raffia palms) but they are one of my favourite birds.

Hi Jill and everybody
Yes Jill unlike the LOG Rooks are quite rare here, only appearing, according to my book, between the Bernesga and the Orbigo and around the Rio Esla, with around 1600 pairs in total.
Interestingly Rooks are around the rookery most of the year, only disappearing into the fields around harvest time and when the fields are ploughed, like plovers and seagulls they often follow the plough. However, around December they congregate around the rookery, it cannot be to find a new mate as rooks generally mate for life, but believe me, yesterday at Villadangos del Paramo, they were there in strength, certainly more then 200 birds, and the noise was amazing, like you I love them as they are so gregarious and to be honest, a thriving rookery is one of natures spectacles, long may they prosper. I have recently discovered a new large rookery the other side of Leon, I will be reporting on that ASAP
Regards
Dave

Greetings Dave and Everyone,
Nice to see this little r nook revived after summer and now with autumn drawing to an end. Looking forward to seeing how the next super-imposed population map contrasts with previous two. What percentage of the estimated 140 new rooks will stick around to build nests in same place come spring?

Super-imposable map of new rookery forthcoming?  :sign:

Was going to do my first (piggy-back/kangaroo) para jump tomorrow, but rain here has stopped play. Just as well, really 'cos I still haven't received my Xmas digital camera ...

Hi All,

One of our bird books notes that…

                     “Noise from a rookery at nest building and mating time can be deafening.”

Dave, remember to take your earplugs for the next count!

Hi Everybody
Quick update on the Rooks
As before Villadangos is streets ahead as far as nest repairs are concerned. This morning was foggy so the birds were hanging around the rookery.
At St Martin, we saw far more rooks than previously, but the nest repairing appears to be on hold. Not possible to park safely, as the fog was obscuring my exit from the farm track, and it was too dangerous to park on the main road.
Will be reporting a count ASAP
Regards
Dave

Hi Everybody
Took a drive into the country today, mainly to collect water from a spring, I thought i would check up on the Rooks
Villadangos    no rooks 30 nests  very quiet
St Martin del Camino   very few nest, but above me a cloud of rooks   Very noisy
Also an large flock of Starlings
On the way back visited the the Storks in San Miguel del Camino, the cormorant roost and the Heronry
Took a few minutes of video, which I uploaded to You Tube
The Video camera is quite old and has difficulty in focusing but I was quite pleased with the result, lots of traffic, so the background noise is quite loud
I hope you like it

Many thanks for that Dave.

At times the traffic sounded like Hitcock's birds...

Is this the first iberianatureforum video?

Greetings Dave,
Thanx for that update - will check out the YouTube video on the morrow when I can access the Technopatlets' PC (mine is strictly for work - OK, and the iberianatureforum - but strictly no YouTubes, eMules or whatevers).

What's your considered opinion on the 30 Villadangos nests - no rooks & very quiet?

Am naively intrigued by how you manage to upload a video to digital format. Does this mean I can digitalise all my video footage? (And if so, can I do the same with all my music cassettes? - don't worry, folks, I've side-tracked Clive on the snowbell thread, and by the time he comes across this tangent...)

Hi Everyone
No it is the second video as the Otters in Asturias beat me. Interestingly the noise at the beginning is not traffic , but the rooks, the traffic was not constant, although I think some camera noise is evident, the noise from the starlings was also quite loud.

Dave

Great video Dave :clapping: I know what Nick means about Hitchcock though, poor corvids always sound a bit scary to me (apart from choughs whose calls I really like.) Looking foward to the next one. Will it have some commentary?  >:D

Thanks for sharing your video Dave.  Incidentally, up in the storks' nest there are two things hanging from the cross, one seems to be a horse shoe and the other looks like a letter A.  Do you know what it is?  With the storks' association with good luck, that's quite a few superstitious symbols crammed together.
