Beskrivelse: Jeg mener, dette er en steppehøg pga af kroppens basisfarve og de relativt kompakte vinger - kontra hedehøgens mere flaksende, lange vinger. Der er jo ikke ligefrem tale om halskrave men to sære pletter i nakken.
Men jeg ser frem til gode bud fra mere kompetente kærhøgespecialister.
BT
Pletterne i nakken er ikke så sære endda.
Alle (eller ihvertfald masser af rovfuglearter) har hvid basis på nakkefjerene, og når disse rejses dannes enter et hvidt felt eller to felter.
Til Lise (som jeg kun kan svare her): disse nakkepletter er ikke et feltkendetegn, så du må til at notere andre dragtdetaljer også:-)
Mvh.
Peter
Hej Bo
Den gamle sag har du ikke fået mange svar på.
Jeg mener, at det må være en Hedehøg. For Hedehøg og imod Steppehøg taler følgende.
De meget lyse markeringer rundt om øjet.
Den lyse halsring afviger ikke i farven fra kroppens farve og har mange mørkere pletter.
Den mørke halskrave er svagt markeret.
Derudover synes hånden relativ lang og bred i forhold til armen.

Nu er det svært at se den øverste del af vingen ordentligt (vinge-tegningerne er den nemmeste måde at adskille de tre ret ens triel-arter i Afrika selvom der kan være variationer, bl.a. hos Water Thick-knee), men der er ikke særligt meget gult på næbbet og det relativt mørke ansigt (ikke særligt markante, hvide tegninger) peger ligeledes på Water Thick-knee.
Triel synes desuden tilsyneladende kun at overvintre ned til Østafrika, hvor den iøvrigt er ret fåtallig.
Og så står den jo i vand...:-)
Apropos navne-debatten kalder sydafrikanerne den for Water Dikkop, et af utallige eksempler på navne-divergens for de samme arter mellem Ø og S-Afrika.
Lars Pip
Et fint adfærdsfoto, men der er næppe nogen tvivl om, at det er en Water Dikkop, der i øvrigt er en ganske almindelig fugl i Kruger.
Vores egen europæiske Triel-art er derimod aldrig set i Sydafrika - sydgrænsen for overvintrende Triel af vores egen art udgøres af det nordlige Østafrika.
De bedste hilsner
Søren Skov
Tak for kommentarerne.
Jeg er enig i, at det må være Water Thick-knee. På Afrikaans: Water Dikkop, hvilket skulle indikere, at den skulle være specielt tykhovedet. Det handler nok om, at den stoler så meget på sin camouflage, at den er svær at få på vingerne - ikke at den skulle være dummere end andre fugle.
Beskrivelse: Kan nogen hjælpe med bestemmelsen af denne sydafrikanske høg. Da den ikke passer med noget i min fieldguide, tror jeg der er tale om en ungfugl. Det er jo tydeligt en høg - byttet er en gnaver eller lille pattedyr - og høgen var 35-40 cm lang. Den sad på en gren i ca 5 meters højde. Kombinationen af stribet bryst, unsfarvet strube, gule øjne og rødlige ben kan jeg ingensteder finde i min guide. Nogen forslag ? Tak. Bo
Hm... after consulting Ole's link and "Birds of Africa south of the Sahara" by Ian Sinclair and Peter Ryan i would prefer Gabar Goshawk. Sometimes size can matter: the Southern Banded Snake Eagle has a size between 55 and 60 cm, the Gabar Goshawk is much smaller, about 28-36 cm. So maybe that can help for a final identification.
Hilsen! Mats
Det er ikke en Gabar Goshawk, da denne vil være langt mere langhalet.
Valget står derfor mellem Southern Banded Snake Eagle eller en Cuckoo Falcon.
Desværre kan man hverken se halen eller baghovedet, hvor Cuckoo Falcon har en top, men normalt ville Cuckoo Falcons øvre bryst være mere grå og selve hovedet meget mere gøgelignende. Fuglen er derfor en Southern Banded Snake Eagle

If this bird was a cuckoo hawk, the head should be lesser and the bill longer.
The whole head in the cuckoo hawk is much more cuckoo-like than this bird. Also on the Cuckoo Hawk the upper chest should be grey - on this bird the upper chest is chestnut.
I still belive this bird is a Southern Banded Snake Eagle.

Hello Bo and others ,
It’s always interesting with pictures like this one , who results in a good discussion. Sadly I don’t think I can help with a definite identification , but I do have some thoughts I would like to share:
In my mind there are five possibilities: Southern banded snake-eagle , two species of chanting goshawks , gabar goshawk and african cuckoo hawk. Bearing in mind that the picture was taken in Krüger NP , southern banded snake-eagle and pale chanting goshawk are certainly not the most likely candidates but can’t be discarded based solely on that.
However , I think that this bird is not a southern banded snake-eagle for several reasons: First of all the snake-eagle is a fairly big bird with a length of 55-60cm which is 50% more than this birds 35-40cm stated by Bo , who also called it “obviously a hawk”. I also think that the legs , being very long , slender and orange , are all wrong for the snake-eagle. Regarding the length of the tail versus the length of the wing , I think that it might not be possible to determine that from this picture. To me the feathers protruding from under the big branch is not tail and right wingtip , but rather either only the tail (split) , or tail and the tip of the left wing – in case of the latter , the left wing would be hanging in an odd way , and thus not of help in determining the length.
Regarding african cuckoo hawk , I think that Søren S. has made a good case of why it’s not that species , and again the legs doesn’t fit the species at all. Therefore this bird is , in my mind , either a gabar goshawk or one of the chanting goshawks.
Obviously it isn’t an adult bird due to the piercing yellow and black eye and the brownish , rather than greyish , overall impression – whether it’s a 1st or 2nd cy bird I can’t say. At first I was also fooled by the coarsely barred lower breast , flank and belly , but after having looked through quite a few pictures of the three species I can see , that this is not at all unusual. Some argues that the tail length is not right for gabar goshawk , and it’s true that this species will often have a conspicuously long tail , but this character is highly variable and I do think that this bird is within the limit.
The colouration of the bare parts (the legs an intermediate colour between the yellow of juveniles and the red of adults) , the length of the legs and the pattern and colouration of the plumage are all consistent with one of the three species , and my guess is that this is either a gabar goshawk or a dark chanting goshawk.
For some pictures of birds looking quite similar to this one , check these links:

- allegedly dark chanting goshawks.
Jon
PS. Do you have more pictures of this bird , Bo?
LBJs (Little Brown Jobs) is a well-known problem when identifying African birds - and a likewise African challenge could be called MBRs = Medium-sized Brown Raptor. Jon has already made a detailed discussed and let me add to this:
To my eye, the key to the identification is at first to forget the plumage and instead focus on some definite structural aspects: Legs, tail/wing length and bill/head proportions: (1) The bill is rather small. This excludes Southern Banded Snake Eagle (which also has even bigger head). (2) The tarsus is thin and long with rather weak feet. This again excludes Southern Banded Snake-Eagle but also African Hawk-Cuckoo. (3) The wing-tip almost reaches the tip of the tail. This excludes - as already pointed out - Gabar Goshawk (and perhaps again the Snake-eagle). The only species to have passed this step-wise analysis is Dark Chanting Goshawk - as suggest by Tau.
Now turning to the plumage the brownish upper breast with some pale on chin, the brownish barred breast/belly, and the distinct reddish colour to the long legs are all characters which fits the immature Dark Chanting Goshawk. One can check additional pictures in the photo-data-base on the web-site for African Bird Club, cf. the links mentioned by Jon.
Characters to exclude the otherwise appealing suggestion of an African Cuckoo-Hawk have already been pointed out by Søren. For Gabar Goshawk it could be mentioned that the bird on the picture does no show distinct white tips to the secondaries, which is an important character for this species (and nicely shown on the Ole’s picture, cf. the link in his comment).
As mentioned by Jon there are two species of Chanting Goshawk in Southern Africa, and the immatures are very difficult. But the Dark Chanting Goshawk is the species to seen in Kruger NP, so I believe it is the likely species.
Hi Uffe ,
I think you’re making some very good points , though I disagree on the tail-/wing length issue. In your step-by-step elimination process you say in step 3 that “the wing tip almost reaches the tip of the tail”. First of all I believe that you – and others – are wrong about that. To me the wingtip is hidden behind the branch and hence it’s difficult to say something definite about the length of it. It seems evident though , that it’s much shorter than the tail and therefore doesn’t exclude gabar goshawk – am I the only one who interprets the picture like that?
Secondly , if you are indeed right about the tail and wing being of equal length , I think you make a mistake in saying that this fact doesn’t rule out dark chanting goshawk. As far as I remember , the chanting goshawks have an almost equally prominent tail extending well beyond the wingtips on the perched bird as gabar goshawk.
The lack of white tips to the secondaries , on the other hand , would normally rule out gabar as you say. I’m not sure if this could be explained by wear , or if this bird could be a 2nd cy bird (if there is indeed such a thing as a distinguishable 2nd cy plumage?) , since I’ve seen other pictures of (alleged) immature gabars lacking this character? If an immature gabar should always show the white tipped secondaries , I think you’re right about the bird being a dark chanting goshawk. If not , I still have my doubts….
Jon
Wingtip is hidden behind the branch...but just visible at the left of the tail, which might add to the impression of the projection between tailtip and wingpoint visavi Chanting Goshawk
JanJ
Thanks Alex and Jan , I guess I don’t need to go and have my eyes checked then , though I can’t actually spot the wingtip to the left of the tail – not with certainty anyway. Had the wingtips indeed reached the tip of the tail , this bird would really have been an even greater mystery…
Best wishes
Jon
Now I see that I might have been misstaken Jon. I took the image upp to 400% to get a better view of the two tiny 'pins' just visible left of the bump on the branch to the left of the tail if you see what I mean?
Anyway, the tail is to short for Gabar, as are the jizz I´d say. But stranger things has happend.
JanJ
I absolutely see what you mean Jan , I just can’t tell for sure if anything in that area is the extreme tip of the wing , or if it’s all just a part of the branch. I agree that this is not an archetypical gabar goshawk with regard to tail length and jizz , but the same could be said about dark chanting goshawk really. However , I still think it’s within what can be explained by individual variation , and jizz can be difficult to assess from a single picture , while proportions sometimes differ in young an adult birds. My best guess is therefore still gabar or dark chanting goshawk , but maybe Bo could offer his thoughts after the input he has received , since he’s the only one who has actually seen the bird in real life?
Jon
Thank you so much for all your comments regarding this little problem. I have been away for a few days, so: sorry for not replying before now.
The bird was definately not a Banded Snake Eagle - it was too small and much more goshawk-like.
So that leaves us with Gabar and Dark Chanting Goshawk.
Considering the size of the bird, I would call it a Gabar. Also I think that the shape and size of the head indicates that it is a smaller bird than the Chanting Goshawk.
I realise that there are some problems concerning the length of the wing compared to the tip of the tail, but perhaps the right wing is not completely folded... so that the tip of the wing seems longer ?
Anyway: I have uploaded two more pictures of the bird, so hopefully we can finally agree on the same species.?
My current bid: 1-2 cy Gabar Goshawk.
Thanks again everybody ! Bo
Hi Bo ,
I’m looking forward to seeing the other pictures of this bird.
Sorry to repeat myself , but I still don’t see the wing-tail problem , since the tip of the right wing is not visible (or only just?) beneath the branch , which the tail certainly is! This means – to me anyway – that there is more than adequate tail-extension for it to be one of the to species – and by the way , I think you’re wright about the right wing hanging a bit.
Jon
I’ve just seen the two new pictures of this species and I’m still not sure. However , when Bo writes that the size was consistent with gabar rather than dark chanting goshawk (and the size difference is considerable) , that might settle the matter. I can’t find any reason why the bird isn’t a gabar goshawk anyway (except for maybe the lack of white tips to the secondaries , as mentioned by Uffe?) , so maybe that’s what it is….
Jon
I took the raptor to BF (some South African birders there)- of by whom none have answered, yet.
I got these though, worth considering:
I don't know pretty much anything about identifying African birds of prey, but I did just some Google searching. Firstly, the bird is definitely a juvenile (there was some discussion about the age on Netfugl), as the relevant species lack intermediate subadult plumages.
IMO there are some features that don't fit Gabar Goshawk (based on a very small sample of photos):
1. The tail looks too short to me. The Gabar Goshawks that I've found pictures of on the net show a very long tail, with the Chanting Goshawks having a clearly shorter one. IMO the length of the tail can be assessed without exact knowledge of the position of the wing tips.
2. The lower breast is uniformly brown. The few pictures of juvenile Gabar Goshawks that I found show a completely streaked breast.
3. The white bars on the belly look narrower than on the Gabar Goshawk pictures on the net.
4. The bird lacks white tips to the secondaries.
Here are some photos of juv Gabar Goshawk (more credible ones):

Here's a Dark Chanting Goshawk:
http://www.martincreasser.com/Kenya%...oshawk-1Fm.jpg
(shorter tail, uniform breast, narrower white streaks on the belly and the secondaries lack clear white tips)
Here's an (at least alleged) Pale Chanting Goshawk for comparison:
http://www.realbirder.com/NamibiaD/B...wkJuvenile.jpg
(note that I'm not at all sure what the subject bird is, just wanted to point out these inconsistencies when compared to Gabar Goshawk pictures)
Hi all,
You are right, this bird is clearly not a Gabar Goshawk, the jizz is all wrong: too bulky, head too big, breast too dark.
I agree that it's an immature Chanting Goshawk (Melierax sp). The ID of young Chanting Goshawks can be quite difficult in area where range of several species overlap.
I think there now 4 species recognized (have to check though):
-Eastern Chanting Goshawk
-Southern Pale Chanting Goshawk
-Northern Pale Chanting Goshawk
-Dark Chanting Goshawk
So Eastern and Northern Pale are ruled out by distribution (pic taken in South Africa). This bird might even be ID'ed on range alone (Kruger N.P). I 'll check in my books tomorrow...
Hi Jan ,
Good idea to get opinions from elsewhere (do you have a link to that discussion?). I’m not quite sure how to read this , your most recent contribution , though. Does it contain any of your own thoughts , or is it perhaps just submissions from two other birdwatchers (one from “I don’t know pretty much…” to “…Gabar goshawk pictures)” and the other from “Hi all, ….” To “… my books tomorrow”)? Anyway , I’ll try to address some of the points raised here:
To take the last one first , I must say that I disagree completely about id’ing the bird on range alone! Of course , looking at the range is always helpful , but to my mind it’s never more than a good indication , and you should never rule out alternatives based on that alone. Having said that , gabar and dark chanting goshawk are the only two relevant “hawk”-species commonly seen in the Krüger NP.
Regarding species of chanting goshawks , I believe that presently (It seems like “splitting” and “lumping” is going on all the time these days) there are 3 generally accepted species: Dark chanting , pale chanting and eastern chanting – the last two formerly considered as one species.
That the bird is “clearly not a gabar goshawk” is a very confident statement. I agree that the jizz is not typical for gabar goshawk , but on the other hand it’s really not a typical chanting goshawk either. Also , as I’ve said earlier in this discussion , I believe that the jizz-issue can be tricky when looking at photos and in particular when you only have one picture – or as is the case here several almost identical photos.
When it comes to the plumage , I don’t know what to believe. The birds I’ve seen myself have all been adults , and I suspect that on the picture found on the Internet the birds might not all have been identified correctly… - some definitely aren’t! However , I don’t think the tail length rules out gabar , even though it is certainly at the short end of the scale for this species , and I’m not sure if the width of the bars on the underside is a definite character either. The lack of white tips to the secondaries and the uniformly brown lower breast could possibly (?) eliminate gabar , on the other hand Bo , who saw the bird , says that the size is more consistent with gabar than dark chanting goshawk so…!
Jon
Ps. Can anyone tell me what the abbreviation IMO , as used above , means?
Hi Jon.
These opinions are taken from Birdforum.net There are some more suggestions there now, with good links to possible species.
IMO = in my opinion
JanJ
Jon.
The suggestions from BF does not contain any of my thoughts, I only brought it there because some South African birders makes suggestions there when dealing wit African species, some of the very good.
I also know that these contributions to the Gabar/Chanting on BF are not based on own experience, at least I think so.
I thought anyway that they might trigger someone else to make sugggestions as to what species we might deal with here. A tricky one this!
JanJ
In my opinion the feathers below the branch are all tail feathers, the tail is worn. The angel of the ving and the angel of the feathers below the branch doesn't fit.
Hi guys ,
Thank you for explaining the abbreviation IMO!
Jan , I found the discussion on Bf (http://www.birdforum.net/showthread.php?t=134506) , and even though there seems to be some consensus there , that the bird is a (dark) chanting goshawk , it made for some pretty interesting reading – again , good idea! The user “CAU” (on Bf) has made a very fine collection of goshawk-photos which is definitely worth checking out. Even though I can’t help feeling that he has picked the pictures supporting his own theory , he might be on to something. What these – and other – pictures tells me more than anything though , is that there are quite a lot of individual (and regional?) variation , and that jizz and proportions are of almost no use in separating the relevant species on some photos!
Therefore , after checking Bf , I just find myself confused on a higher level regarding this bird. When looking at the plumage , I lean towards one of the chanting goshawks. From this photo alone , the jizz and proportions doesn’t point one way or the other to me , but I think (like Steve G on Bf) that gabar and chanting goshawks should be fairly easy to separate in the field based on just that. That is why I think it is important when Bo (the observer) calls it a gabar!
The one thing I have certainly learned from this discussion is , that the field guides leave a lot to be desired when it comes to identifying juvenile/immature gabar and chanting goshawks. The illustrations vary quite a lot , and some seem to be way of , so there are definitely something to improve here.
I wonder if this bird will ever be identified with any certainty. There seems to be supporters of both gabar and the chanting goshawks , and even if it is indeed a chanting goshawk there is still the question of dark vs. pale!
