Thanks for the update Gretchen.
That pair aren't doing so well, then.
Wonder if one or both are old?

Well, wish it was better news on the very non-chick-like egg. I have no idea about the parents - just picked up a few bits and pieces in passing as I have quick scanned the osprey blog (here - some of them have their eyes on multiple nestcams ;)). I'm not sure if anyone is recording their observations of this nest systematically - that is, someone who has more time to watch than I do!

Is an unhatched egg pretty rare then? Do you know what might happen next?

Thanks for all your info and insights, H2. Have you been watching hobbies for several years?

Unhatched eggs are uncommon, rather than rare. Infertility in many species is often age-related.
I don't know if the Hobbies will try (or even if they are able) to remove the egg. I think it might just remain there.

I've been enjoying Hobbies for many years - but it's only relatively recently that they started nesting this far north - so in the past my observations were restricted to visits to more southern spots.
Last year was the first time I started watching a nest on a regular basis. (I had previously found one during a holiday in Dorset - in August with just-about-to-fledge chicks - I can still recall the fantastic sight now.)

If the shooters return you can get them stopped by the Police - if they are disturbing the breeding birds - it's not always easy to get them to act, but worth a try.

Thanks Joanne.
Have you had a look at the New Forest nestcam recently - did you read my post re same?

H

I haven't been watching it much but now that I know they've hatched I will look more. Interesting but not surprising, what you say about age and infertile eggs. I watched this nestcam last year and this pair only fledged one chick, the other two died.

Not the most productive pair are they.

Not the most productive pair are they.

It seems not.

Question re IDs: The New Forest female (I'm assuming it's the female) has a white spot on the back of her head. I've seen this on some hobbies but the books don't always show it. Is it a variable thing? Just the immatures and females? You seem to be confident in sexing your hobbies, any tips? I can tell the young ones, given good enough views, but not able to tell the males from females.

Hi Joanne,

All the Hobbies I've seen have double pale (not white) patches on the nape, separatd by a vertical dark bar. Sometimes just one is visible. A few birds have these - especially smaller owls - I think they resemble eyes and help to give the impression that the bird is always looking at you even when facing away.
This varies a little in the size & shape of the patches - my pair vary a bit in this respect - much as they vary in many aspects of plumage detail.

On the separation of the sexes - I presume you are referring to my posts above (Jos's photo, and the female intruder)?
On the photo the relatively large head size in comparison to the slim body is usually a good pointer - though, like any bird, they can & do fluff themselves up & make this impossible at times.
The intruder female today was so much bigger than the male that her sex was obvious. At distance/height a female circling slowly can even have a Peregrine look about them - something that I don't find in the case of males.
My male is strikingly slim winged and bull headed - almost parakeet-like in outline. This of course also varies depending on flight attitude - birds of prey can flex their wings to appear broader or narrower depending on purpose: watch a falcon change from soaring to full-on flight and notice this - so a practised eye is needed. When the pair are in full swing it's near impossible to separate them.

Thanks for tips. I'll try to focus on head size in future. Trouble is.............I just don't see enough of them.:stuck:

Glad you've made it back out into the field H.

Not had chance to get there myself, but I did glimpse a Hobby near Arnside in Cumbria this morning - so it wasn't a completely wasted day !

Joanne,
In this photo (if the link works!) I think this is a female: a male never looks as broad winged.

This however looks big headed - male.
http://www.errigoiti.com/mediac/400_0/media/DIR_1758/Falco$20Subbuteo$20-$20Alcotan.jpg

This one looks male to me:

This is broad-winged - female?
http://www.zgapa.pl/zgapedia/data_pictures/_uploads_wiki/f/Falco_subbuteo_kobuz2.jpg

Sorry - second link doesn't work - but have a look at images on the net - a lot are seperable - others are not to my eyes.


Female I think:

Again female:

I've just corrected some wrongly input images there - sorry if I confused anyone - I think the remainder are correct!

OK I think that's enough - but I think you'll agree that there's a difference.

July 21st. Teeth of the Gale

14:15 - 16:00

Rain all day finally stopped but wind continued to increase.

A half-gale was blowing the nest tree about manically. The nest itself like the crow's nest on a storm-tossed galleon, upon which the female sat impassively.

Everywhere the sky was full: Swifts blown backwards and struggling on into the wind, a flock of House sparrows on the crop top like petrels on the foamy sea, Swallows spiralling, and hundreds of Wood pigeons in clouds, below torn clouds which were finally giving way to blue.

Then, there was the male Hobby - into the gale's teeth, battling on as hirundines and Swifts swarmed around like fish before the shark. He went behind a tree and was gone - his switchback signalled by those following, but lost.

Half an hour: there again, now clockwise around the territory, in from the west. Gone as quickly once more. A Kestrel attempted a hover - blown into an up-pitched scrag of feathers and sinew - then gave up to catch the wind and whip away to find a steadier perch.

The female Hobby kept lookout, leaning half-in and half-out of the nest, facing away, peering out from the pitching, seasick tree. Linnets' and Yellowhammers' calls blew along the hedges.

Again - a meteor-fast vertical arrow disappearing behind the trees, dark lightning. Next: up into the howling sky - rising like an express lift towards bouyant Swifts - and away down the wind, still climbing and trying for the elusively swift prey. Within a minute he was a speck against a huge black cloud and lost to distance.

He had been flying, to my knowledge, in this maelstrom day, for over eighty minutes when the cries came battling through the baffling wind: he had been successful. She slipped off the swaying nest and went to meet him. Seconds later he was on the perch tree wiping his now empty bill, at rest at last.
Then he was up - and they were both flying together towards a hidden perch - and she was carrying the prey - distinctly pied - perhaps a House martin. Away to pluck briefly - then a dark arc brought her back to the nest and her young.

As the wind obscured my visual window on the nest intermittantly, and vibrated my 'scope (as well as trying to knock me sideways!) I didn't have the best of views - but I could make out two fluffy white heads looking up at their mother, who began the feed them.
I can't be sure - but once or twice I thought a third head was briefly visible.

I hobbled back with a smile on my face - another great interlude in another world.

The Late Show

19.30 - 21.00

Decided to make a late visit as the sun was shining at last and the wind was on the wane.

Tonight's strategy was to stay in one position and watch the nest to wait and see what transpired.

The female sat facing away on the nest but was easy to see as she is now riding several inches higher, presumably due to the growing chicks beneath her.

The light was perfect with the setting sun illuminating the site in the best way possible.

No sign of the male until 20.37 when he could be heard calling from the far side of the trees. Immediately the female left the nest and disappeared out of view for about 3 minutes. She then returned with the prey the male had obviously just passed to her out of sight. I couldn't tell which type of bird it was as she stood facing in my direction and started tearing strips of meat for the fledglings.

Like two glove puppets, two small white heads began to appear bobbing up and down, sometimes alternatively and sometimes together, but I'm sure there are only two chicks.

It was quite a dramatic scene, almost a connection with pre-history, the dying sun casting a fiery glow over this magnificent, pitiless raptor in it's own private world.

Vivid reports as usual, but, 'pitiless raptors', John? That's a little harsh. They're only trying to feed the downy bundles of joy.;)
As usual, I thoroughly enjoyed reading the latest. Thanks H and all you Hobbiests.

July 22nd.

10:30 -11:45.

Windy, squally showers.

Wind a little less powerful today - dark black and grey clouds just off west - rain threatening ever closer. Sky full of Swifts (should the young be on the wing by now?).

The female sat bolt upright on the nest's edge - facing me - watching for her mate's return, but, though once the Swallows' alarms indicated him as visible to them, I didn't catch a glimpse.

As the temperature dropped and the first specks of rain fell I headed off.

Anxious Moments

H

Almost went this morning at the time you were there but changed my mind.

15.15 - 17.00

Alarmed to find neither bird on the nest, and no sign of chicks either.

After 25 minutes still no sign of either parent. Then, just as I was becoming really concerned that something was wrong, the female entered the back of the nest - relief !

She didn't appear to have any food, so not quite sure where she had been ( any ideas H ? ) She then just seemed to stand around in the middle of the nest for a few minutes before settling down to preen herself.

Another hour on and still no sign of the male, until suddenly he appeared just above the tree line hanging in the wind, only to quickly disappear back amongst the tree's. There was no calling and no apparent interaction with the female who remained impassive on the nest.

By 17.00 it was time to go, but over the 90 minutes I was there, no food was brought to the nest. Maybe the male was having a rest - girls can be very demanding !!

John,

I'm not surprised you were anxious, I would have been.
Let's hope it's nothing untoward.
We could just have got our timings wrong - and have just seen a quiet spell.
The female would have been nearby, I'm sure.

U, Still quiet here on the dragon front. Hardly a one for weeks.
Those Hobbies should be getting noisy soon - still time.

July 23rd: 5 Hobbies, 15 Crossbills!

08:30 - 10:45

Warm, intermittant sun, a shower.

After last night's news I was fairly anxious to be there this morning. But - there was the female on the nest as normal.
Was joined by Sid and Voirrey soon after and so three 'scopes were trained on the nest.

A Sand martin or two joined the local Swallows - one even perching on a telegraph wire right above us. But not long in a flock of bulky finches flew low right over head - almost directly north-south.
I managed to pick out one very pink male Crossbill - and we watched them carry on out of sight.

It was quite a long time until the familiar calls from the trees: but the female didn't get out of the nest. Silence again. Several minutes passed. Then, the male was on top of his perch tree: and she was gone from the nest.
A few more minute passed: she flew back to the nest and began to feed the young with what the male had passed to her, in silence. Presumably he'd had a quick feed from the victim before his mate got it.

Two white heads could clearly be seen - their mother feeding scraps of the prey to them. Try as I might I couldn't see more than the two, though.

Before the meal was over I heard a territory-disputing "kwif-kwillif kwif" sort of call from way up. Looking heavenward I made out two male Hobbies - with a crowd of hirundines even higher.
We had an intruder male!

With no particular antagonism the two males drifted and circled - one going for a Swift briefly. Occasionally we lost one or the other against high bright clouds - but both eventually were circling to the south west not far away. They had been up hunting for many a minute - but neither caught anything.

Then the male circled back and gained height again - still hunting - before closing his wings entirely and falling like a stone to the trees. At full speed he disappeared behind, then rocketed back up a little, and swerved out of sight. But soon he was back on his perch, the intruder gone. We never got a view good enough to age him. These two intruders make me wonder if they were last year's young.

A Buzzard or two came past - and the male was up and screaming at it - diving at the big predator. Then both the pair of Hobbies were in the air together - attacking the too-close Buzzard - until it was at a safe distance from the nest.

The male went back to the perch tree, she flew around for a few seconds, then sat beside her mate. They stayed together for a while, both in good light and giving us excellent views, then she was back to the nest.

As we left he was gone again. It had been quite a morning.
