039 | ORYX ONTOUR BIRDLIFE REPORTS

39
Dear birding friends, 

as birdwatching is a relatively new and one of the fastest growing and a most popular pursuit, it attracts people of all ages around the world. There can hardly be a better place than southern Africa (Namibia, Botswana, Zimbabwe, Mozambique, Swaziland, Lesotho, South Africa) to nurture an interest in birds as it supports almost 1000 bird species, which is about 10 per cent of the world's entire bird. Taking birding to new heights Hobby-Ornithologist Stefan Rust represents some of the ontour bird sightings to showcase the fun of birding, promote citizen science, highlight conservation, indicate where to view what birds and raise awareness of southern Africa's (sometimes international) birds and their habitats. 

Oryx (Namibia) Ontour Birdlife Report: 

30.10.'12   Onjala Lodge   Rockrunner (10)   This near-endemic species can easily be viewed in the surrounding. 

31.10.'12   Onjala Lodge   White-backed Vulture (18)   In S.Africa, Lesotho and Swaziland classified as vulnerable. 

31.10.'12   Onjala Lodge   Lappet-faced Vulture (11)   In S.Africa, Lesotho and Swaziland classified as vulnerable. Only ±40-50 breeding pairs in Namib Naukluft Park, Namibia. 

31.10.'12   Onjala Lodge   Verreaux's Eagle-Owl (2)   One adult and one Juvenile. For Namibia egg laying dates are not mentioned. Incubation and development of young lasts ±100 days. Obviously adult must have started laying approximately mid June. Laying dates are recorded for Botswana in Sept.-Oct., for Zimbabwe May-Sept. Because it breeds only every 2-3 years and low density this species is regarded as vulnerable. I had the chance to analyze its prey in detail (not mentioned for Namibia before and some prey items have not been recorded before): Mammal, Ostrich eggs (possibly newly hatched ostrich chicks with eggshells sticking to moistures down-feathers), skunk, large moth, Helmeted Guineafowl, Savannah Monitor and fresh shoots of Acacia tree. More detailed report available. 

31.10.'12   Onjala Lodge   Freckled Nightjar (1)   On eastern border of Namibian distribution. Mica-schist rocky riverbeds are ideal habitat. 

31.10,'12   Onjala Lodge   Orange River Francolin (4)   Although considered as not threatened, reports indicate that populations decrease severely because of regular grass burning and poor grazing management (overgrazing and cultivation)(especially in "well-managed" nature reserves).

01.11.'12   Onjala Lodge   Cape Glossy Starling (1)   Gleaning ectoparasites from back of Common Warthog (Phacochoerus africanus). More detailed report available. 

01.11.'12   Onjala Lodge   Burchell's Starling (2)   Associated with Common Warthog feeding on ground nearby. 

01.11.'12   Otjiwarongo (40 Km south)   White-backed Vulture (8)   In S.Africa, Lesotho and Swaziland classified as vulnerable. 

01.11.'12   Otjiwarongo (10 Km south)   Verreauxs' Eagle (2adult,1juv.)   Only in Namibia considered as near-threatened due to small population. 

01.11.'12   Outjo district   Steppe Buzzard (1)   Palearctic-breeding migrant arrived. 

01.11.'12   Gelukspoort   Chestnut Weaver (large flocks)   Regarded as most abundant Weaver in Namibia. Large flocks to be seen, comparable to those of Red-billed Quelea. 

01.11.'12   Gelukspoort Gaestefarm   Bare-cheeked Babbler (11)   No research on the incubation is done of this uncommon to locally common bird. 

02.11.'12   Gelukspoort Gaestefarm   White-browed Scrub-Robin (1)   There are 3 geographical variations recognized for southern Africa. For north-western Namibia the less heavy streaked race Cercotrichas leucophrys ovamboensis is reported. Here on Gelukspoort (situated in north-western Namibia) I found a member of the not for Namibia registered heavily streaked race Cercotrichas leucophrys leucophrys. Contact me for a more detailed report. 

02.11.'12   Gelukspoort Gaestefarm   Augur Buzzard (1)   These long-living birds can reach an age of up to at least 9 years. 

02.11.'12   Gelukspoort Gaestefarm   Black-backed Puffback (1)   As typical for this species only the female built the nest. 

03.11.'12   Etosha N.P.   Southern Pale Chanting Goshawk (1)   Observed how it hunted and then fed on a Monitor Lizard. 

03.11.'12   Etosha N.P., Okondeka   Southern Pale Chanting Goshawk (2)   They started nesting. 

03.11.'12   Etosha N.P., ±3Km north of Okondeka   White-backed Vulture (2)   Nesting on Umbrella tree. 

03.11.'12   Etosha N.P., halfway Okaukuejo/Okondeka   White-backed Vulture (24)   Feeding on carcass. 

03.11.'12   Etosha N.P., halfway Okaukuejo/Okondeka   Lappet-faced Vulture (24)   Feeding on carcass. 

03.11.'12   Etosha N.P.   Secretarybird (1)   Is the Namibian population decreasing? 

04.11.'12   Etosha N.P.   Cape Crow (±20)   Many are nesting. 

04.11.'12   Etosha N.P., Gemsbokvlakte waterhole   Black Kite (1)   It rained last night and most probably this is the reason for its occurrence. They are known for following local rain. 

04.11.'12   Etosha N.P.,halfway Okaukuejo/Ombika   White-backed Vulture (27)   Feeding on carcass. 

04.11.'12   Etosha N.P.,halfway Okaukuejo/Ombika   Lappet-faced Vulture (6)   Feeding on carcass. 

04.11.'12   Etosha N.P., Okaukuejo   Shaft-tailed Whydah (1)   Male already in full breeding plumage, this is early according to Roberts V11.

04.11.'12   Etosha Safari Lodge   Martial Eagle (1)   Regarded as endangered in Namibia. 

05.11.'12   Khorixas, 10 Km east   Martial Eagle (1)   Regarded as endangered in Namibia. 

05.11.'12   Fransfontein Mountains   Augur Buzzard (1)   These long-living birds can reach an age of up to at least 9 years. 

05.11.'12   Twyfelfontein   Verreauxs' Eagle (2adult,1juv.)   Only in Namibia considered as near-threatened due to small population. 

05.11.'12   Camp Kipwe   Rueppell's Parrot (8)   Near endemic to Namibia. Because of sparse vegetation this is a perfect place to spot these species. 

05.11.'12   Camp Kipwe   Pearl-spotted Owlet (1)   Because of thin tree canopy, the habit of showing "false" face can easily be observed. 

05.11.'12   Camp Kipwe   Damara Hornbill (1)   Still its population size is unknown and needs observation. 

06.11.'12   Uis   Rueppell's Korhaan (2)   This is a near-endemic species to western Namibia. 

06.11.'12   Omandumba Gaestefarm   Carp's Tit (1)   Near-endemic to Namibia. These birds are attracted to the farmyard of Omandumba. 

06.11.'12   Omandumba Gaestefarm   Rosy-faced Lovebird (10)   Visit this family-managed place and observe the interesting habit of this bird of the female carrying its nesting material in its rump feathers. 

06.11.'12   Hohenstein Lodge   Rueppell's Parrot (4)   Near endemic to Namibia. 

07.11.'12   Swakopmund   Cape Wagtail (3)   Two seen with crippled toes and one without toes at all on one foot. 

07.11.'12   Swakopmund River   Greater Flamingo (±250)   Regarded as vulnerable in Namibia. Found 5 carcasses, cause unknown. Contact me for detailed German report. 

07.11.'12   Swakopmund River   Lesser Flamingo (70)   Regarded as vulnerable in Namibia and globally as near-threatened. Population decreases across Africa and threats to the only 3 breeding sites are causes for this conservation status. 

07.11.'12   Swakopmund River   Maccoa Duck (2)   Uncommon in Namibia, a census in 1992 revealed a number of only 899. 

07.11.'12   Swakopmund River   Black-necked Grebe (6)   Thought of not being resident anywhere in southern Africa. 

08.11.'12   Walvisbay Lagoon   Greater Flamingo (100's)   Three dead, cause unknown. Contact me for detailed German report. 

08.11.'12   Walvisbay Lagoon   Lesser Flamingo (1dead)   As far as I'm concerned this is the first dead one of this species to be reported. 

08.11.'12   Namib Naukluft Park   Common Ostrich (2adult,6chicken)   Half grown chicks. 

08.11.'12   Namib Naukluft Park   Southern Pale Chanting Goshawk (±15)   Many Juvenile birds. 

08.11.'12   Namib Naukluft Park, near Ghaub R.   Tractrac Chat (1)   Near-endemic to southern Africa. 

08.11.'12   Namib Naukluft Lodge   Sociable Weaver (Colony)   Chicken in nest close to Lodge setup. They are thought to breed only in response to rain. But because no rains have fallen, that could have triggered breeding, I suggest that they have enough food supply through getting fed by lodge and there is a fixed waterhole nearby. This colony is thus not necessarily dependent on natural rain and food. 

08.11.'12    Namib Naukluft Lodge   Mountain Wheatear (2)   Juveniles, meaning they succeeded one clutch already. 

08.11.'12   Namib Naukluft Lodge   Cape Eagle-Owl (2)   Extensive range in Namibia. 

08.11.'12   Namib Naukluft Lodge   White-throated Canary (15)   Due of having 42% of Namibian surface under conservation, this near-endemic species to southern Africa is well presented in Namibia. 

09.11.'12   Sossusvlei   Ashy Tit (1)   On western edge of distribution. 

09.11.'12   Sossusvlei   Swallow-tailed Bee-eater (3)   On western edge of distribution. 

09.11.'12   Sossusvlei   Bokmakiri (1)   On western edge of distribution. 

09.11.'12   Sossusvlei   Ludwig's Korhaan (1)   Sparse species in this region. 

09.11.'12   Soft Adventure Camp   Martial Eagle (1)   Regarded as endangered in Namibia. 

09.11.'12   Soft Adventure Camp   Spotted Flycatcher (1)   Arrival of summer visitor. On western edge of distribution. 

09.11.'12   Namib Naukluft Lodge   Pale-winged Starling (1)   Makes use of a wall lamp to roost to have warmth by the light, a snack by preying on attracted insects and protection of enemies during nighttime. Small article on this in German available. 

10.11.'12   Helmeringhausen (nearby)   Secretarybird (2) 

10.11.'12   Garub Waterhole   Greater Kestrel (10)   Nesting in nests of Cape Crow on Telephone poles, sometimes in proximity of Pied Crow (probably using them as defense). 

10.11.'12   Garub Waterhole   Burchell's Courser (2)   Although abundance have decreased over the past 50-150 years in southern Africa, there is no proof of decreases in dry and protected areas of Namibia. 

10.11.'12   Garub Waterhole   Tractrac Chat (2)   Near-endemic to southern Africa. 

10.11.'12   Eagles Nest   Ludwig's Korhaan (1)   Sparse species in this region. Considered as an important role player in the ecosystem of the Sperrgebiet N.P. 

10.11.'12   Eagles Nest   Long-billed Crombec (2)   On edge of western distribution. 

10.11.'12   Eagles Nest   Common Ostrich (4 chicks)   Chicks ± 3.5 months old. 

10.11.'12   Eagles Nest   Tractrac Chat (3)   Perfect place to spot this Near-endemic species to southern Africa. 

11.11.'12   Eagles Nest   Fiery-necked Nightjar (1)   This species has not been registered for this area. 

11.11.'12   Sperrgebiet N.P.   Cape Crow (11)   One nestling was fully feathered, concluding they started breeding begin of October. There are no reports of breeding times for Namibia in Roberts Birds of Southern Africa. 

11.11.'12   Sperrgebiet N.P.   Ludwig's Korhaan (4)   Sparse species in this region. Considered as an important role player in the ecosystem of the Sperrgebiet N.P. 

11.11.'12   Sperrgebiet N.P.   Karoo Korhaan (3)   This species is mainly confined to the Karoo desert and is endemic to southern Africa. 

11.11.'12   Luederitz   Greater Flamingo (±300)   Regarded as vulnerable in Namibia. 

11.11.'12   Luederitz   African Black Oystercatcher (6)   Globally regarded as near-threatened. Stable population around Luederitz. 

11.11.'12   Luederitz   Cape Cormorant (25)   The population of this near-threatened species decreased from 554 000 birds in 1981 to 144 000 birds in 1996 in southern Africa. 

11.11.'12   Luederitz   Cape Gannet (17)   They got the label of "specially protected" bird in Namibia. 

11.11.'12   Luederitz   Bank Cormorant (2)   Also listed as "specially protected" bird in Namibia. 

11.11.'12   Luederitz   Cape Teal (6) 

11.11.'12   Eagles Nest   Black Kite (1)   Although regarded as not often to be found in arid areas such as here close to Aus I found it here. Officially this species has not been seen here before.

12.11.'12   Eagles Nest   Karoo Korhaan (1)   This species is mainly confined to the Karoo desert and is endemic to southern Africa. 

12.11.'12   Eagles Nest   Ludwig's Korhaan (3)   Sparse species in this region. Considered as an important role player in the ecosystem of the Sperrgebiet N.P. 

12.11.'12   Aus (20 Km east)   Black-chested Snake-Eagle (1Juv.) 

12.11.'12   Aus (160 Km east)   Secretarybird (1) 

12.11.'12   Canyon Lodge   African Red-eyed Bulbul (25)   It is remarkable how many individuals got a clearly longer and more curved bill than one is used from this species. See my German article about this. 

12.11.'12   Canyon Lodge   White-throated Canary (19)   Due of having 42% of Namibian surface under conservation, this near-endemic species to southern Africa is well presented in Namibia. Observed one feeding on berries of "stinkblaarboom". 

12.11.'12   Canyon Lodge   Cape Eagle-Owl (2)   Extensive range in Namibia. The prominent roost in a dense-leafed tree in a dry watercourse is marked by signs of thick white droppings, large pellets and prey remains on the ground beneath the tree. An analysis revealed mainly small lizards, many beetles and grasshoppers and a few rodent prey. 

12.11.'12   Canyon Lodge   Freckled Nightjar (1)   Out of its shown distribution. 

13.11.'12   Keetmanshoop Lake   Great White Pelican (52) 

13.11.'12   Kalahari Farmhouse   Acacia Pied Barbet (1)   Feeds "flower" beetle to chicks. 

13.11.'12   Kalahari Farmhouse   Common Waxbill (35)   Uncommon large flock for this area. 

13.11.'12   Kalahari Farmhouse   Pin-tailed Whydah (6)   Male completed moult into breeding plumage. 

13.11.'12   Kalahari Farmhouse   African Hoopoe (1)   I assume that the drastically growing bush encroachment encourages the spread of nest-competing birds such as the Acacia Pied Barbet which then can outcompete the African Hoopoe. 

13.11.'12   Kalahari Farmhouse   African Pipit (18)   This bird has definitely benefitted from the large-scale agriculture by the Gondwana Group for supply for their self-sufficiency concept. This Pipit has clearly expanded its range towards Stampriet within the last few years. 

13.11.'12   Kalahari Farmhouse   Karoo Thrush (2)   This bird has also definitely benefitted from the large-scale agriculture by the Gondwana Group for supply for their self-sufficiency concept. The female had clearly visible orange eye rings, similar to that of the Kurrichane Thrush. 

13.11.'12   Kalahari Farmhouse   Sedge Warbler (4)   Not registered for this area. This bird has definitely benefitted from the large- scale agriculture by the Gondwana Group for supply for their self-sufficiency concept. 

13.11.'12   Kalahari Farmhouse   African Reed-Warbler (12)   Not registered for this area. This bird has definitely benefitted from the l large-scale agriculture by the Gondwana Group for supply for their self- sufficiency concept. 

Enjoy birding,
