Ospreys beginning to make their appearance known

Male Osprey

We have been studying our three cameras closely here at the Wildlife Watch, hoping to catch a glimpse of our Ospreys to see what they are up to. Although no activity has been noted on camera 2 since the beginning of April, our Green DX Male has been spotted on the nest on camera 1 twice in the past week.

Camera 3 has also seen regular activity with a Green ringed Female and an un-ringed Male appearing on the nest on a number of occasions. This looks very promising as we have witnessed a number of mating attempts. The female spends most of her day on the nest only departing when the male arrives with fish.

Our Pine Marten friends have also been making good use of the squirrel feeders onsite and have been regular visitors this week.

Good signs and a fair bit of nest activity from our birds. Hopefully we will be seeing a lot more of them in the coming weeks.

Osprey's return for 2012 Season!

As many of you may have read the Aberfoyle Osprey season is just about to begin. This year for the first time ever we are showing three live nests, two of which are being shown through HD. We have already had ospreys on all three nests and signs of attempted mating between pairs.

On nest site 1 (the nest that we have shown in previous years) we have already seen the return of Red 6A (our female from 2006 - 2010) who failed to return to the nest at the beginning of the 2011 season, but was seen on site later in the year. She seems to have been joined by a metal ringed male, whom we presume is the infamous male from the last few years.

For those of you that want to follow the action minute by minute we will be tweeting @aberfoyleosprey and also Facebooking at www.facebook.com/aberfoyleospreys. We are also hoping to get the webcam link up and running this week, sorry for the delay in this :-)

Other sightings and live cameras currently on show at the David Marshall Lodge Visitor Centre include Barn Owls, Red Squirrels and for the last few weeks we have been catching a glimpse of a Pine Marten, but we are keeping our eyes fixed on the osprey nests as another season at Aberfoyle begins!

Third time lucky for Aberfoyle Nest?

As many of you are already aware there has been a highly contested battle for the Aberfoyle osprey nest this season. It is only just over 2 weeks since the ospreys returned and we have already had 5 different ospreys on the nest (3 females and 2 males). We currently have a metal ringed male, who was the "trouble maker" last year, who kicked out the eggs at the beginning of May 2010 and a new female who is unusually totally unringed! This new female has been around since Saturday and things are looking promising. There has been lots of nesting material brought in as well as repeated mating taking place. It is a year ago tomorrow (Tuesday) that we had our first egg last year, so we shouldn't have long to wait, fingers crossed!

Ospreys have landed!

We can now confirm that ospreys have returned! At around 9.45am this morning Yellow OU, our female from a few year back, and Green DX were spotted back on our live nest site! They have already been seen mating and sorting out the nest. Yellow OU has not been seen on this nest site for number of years, and successfully raised chicks here back in 2005. Red 6A our usual female hasn't been seen yet, and neither has our troublemaker from last year, the metal ringed male! I think there are still a few more twists and turns in the story before we even see eggs being incubated. Stay tuned for more info!

Its not good news........but there is a sliver (ringed) lining!

Our resident male osprey (unringed) has not been seen for about 10 days now and at about the time he disappeared the female appeared to be sitting on eggs. As said in my previous post she is sitting tight most of the time but is getting on and off the nest to chase intruders. This is not good due to the risk to the eggs.

The silver-ringed male has at last been seen providing her with fish. He flew in on Monday with a fish, gave it to her and she flew off. He looked as if he was going to take over incubation but stood in the nest cup then didn't sit down. He poked around in the nest and I watched him with baited breath, half expecting any eggs in the nest to come flying out any minute. Instead he stood there for a moment then took off. The female was sitting in a dead tree to the left and sat there eating her fish for 5 minutes then flew down to the nest with the fish and continued to eat it there. I breathed a sigh of relief and was at least glad to see that she is getting fed. The silver-ringed bird continues to try and mate with her but she is not receptive.

On Tuesday a green-ringed bird landed on the nest and the silver-ringed bird was very quick to defend the female and the nest and actually locked talons with the intruding male. The female joined in quite aggressively and forced them both off the nest. I haven't seen such physical contact in a long time. Ospreys like most animals tend to avoid aggressive contact as it may result in injury; which can sometimes be too costly.

To say our female is having a hard time is to put it mildly, trying to incubate the unringed male's eggs, while trying to defend the nest, most of the time alone. The only good thing is she is actually being fed by the silver ringed male, which is allowing her, for the moment, to continue to sit tight.

I have asked that the cameras be switched from the overview camera to the nest cup camera so we can definitely see if we have eggs and how many. This hopefully should be done today or tomorrow. I'll let you know when I do.

Nearly there?

Tomorrow will be a week since the original male returned and we normally say eggs will appear 7-10 days after mating! The female has been sitting quite low today and fussing about the nest which is a good indication she is getting broody.

The male on the other hand has been very lacklustre today, although he has mated successfully several times with the female.

Both ospreys were alarm calling at certain points throughout the day but no osprey intruder was seen on camera, although a pheasant was seen strolling in the background.

So will tomorrow be the day we see an egg?

All change... again!

The mating between Red 6A and the green-ringed male was improving and seemed to be going well all week. He was adding the occassional branch to the nest and bringing in fish, although I was a bit surprised by his laissez-faire attitude.

Then on Saturday, as soon as the cameras were on, it was an unringed male who was on the nest and green ring was nowhere to be seen. Was this our original bird or another unringed male? The fact our female was so relaxed with him indicated the former, and on checking footage from 2007, it is indeed our resident male. He is quite distinctive as he has 2 stripes coming up from each eye to the top of his head. A marking I have never seen before in another osprey.

It's funny how when you have resident birds together their behaviour just gels and things progress so much faster. This male is on a mission and keeps bringing stick after stick back to the nest. After being off for 2 days I notice a definite improvement in the nest; it is much more formed and is greener, having been lined with moss and lichen. The male has been successfully mating with the female all week and bringing numerous fish to her, including a jack pike. Now that this male is in, things seemed to have settled down on the nest with no other ospreys venturing in for a while now.

Now we can get on with the business in hand!

Menage a ...quatre?

On Monday when Red 6A arrived, the green ringed male tried to mate with her but she was having none of it and kept shrugging him off. She then did have a successful mating, but with which male we are unsure. It seemed too adept to be the green-ringed male and shortly after this mating he did try and was shrugged off again.

On Tuesday there was alot of to and fro'ing on the nest by Red 6A and the green-ringed male, with quite a few sticks brought in.

On Wednesday we finally got to see a fish being brought in by the green-ringed male. He was sitting eating it quite happily at the top of the nest when he dropped it. Red 6A, not one to miss an opportunity, nipped in and took the fish off to a nearby tree to eat it.

Shortly after when Red 6A was on the nest with green ring, another 2 birds joined the proceedings; the silver ringed male and an unringed bird. The latter was thought to be a male due to Red 6A's lack of response but could have been the previously unringed female. Talk about confusing!

Today there has been much nest building going on by Red 6A and green ring. However, although he keeps trying to mate with Red 6A, any attempt has been unsuccessful.
