Family Pyxicephalidae
Identification
The KwaZulu Caco is a small frog that attains a maximum size of 28mm. It is, however, more robustly built than other Cacosternum species. The dorsal surface is smooth to finely granular and varies from dark brown to grey. There is often a pale brown vertebral stripe with black edges and a dark, backwards-pointing bar between the eyes. A dark facial mask runs from the snout, through the eye, to the base of the fore arm. A pale skin ridge is found below the facial mask, extending from the corner of the mouth to the base of the forearm.
The undersides are pale with conspicuous, fused black blotches, and the throat area is dark and densely mottled.
The eyes are bulging and visible from below. The tympanum is visible.
The KwaZulu Caco is most likely to be mistaken for the Bronze Caco Cacosternum nanum (see Similar Species below).
Habitat
The KwaZulu Cacofrequents marshes, streams, pools and flooded grass in savanna woodlands.
Behaviour
The KwaZulu Caco was described in 2013, so very little is known of its life history. The advertisement call consists of repeated pulsating chirps as well as some slower clicks.
Status and Conservation
Data deficient. The KwaZulu Caco is not considered threatened.
Distribution
The KwaZulu Caco is endemic to South Africa and is restricted to a few scattered localities in central Kwa-Zulu-Natal.
There is currently no map available for this species.

31 March – 04 April 2023: Autumn Atlas Bash – Khoisan Karoo Conservancy
The Virtual Museum
The first question asked when the conservation status of a species is considered is: “Where does the species currently occur?” So up to date distribution maps are a priority. This is the objective of the Virtual Museum.
In March 2022, more records were submitted than in any previous March. The final dot on the RED line is therefore BestMarch, by a margin of 657 records. The 12,236 records for March is the fourth best month ever!
Already in April 1,184 records have been submitted. The target for BestApril is 10,348.
Thanks, Team Virtual Museum, for your ongoing contributions. Don’t hesitate to submit common species for well covered grid cells. All species in all grid cells need to be “refreshed” regularly. This prevents the distribution maps from going out of date.
BDI Bird Ringing Course
The BDI will be hosting a bird ringing course from 31 October to 6 November 2022 at New Holme Guest Farm inside the Khoisan Karoo Conservancy, near Hanover in the Northern Cape.
The course will be led by Dieter Oschadleus. Dieter was Bird Ringing Coordinator at SAFRING for 20 years and has tons of bird ringing knowledge and experience. This course is the perfect opportunity for both trainees and registered ringers. You don’t want to miss out on this awesome chance to ring birds in the Karoo wilderness!
The photo collage was made by Melisa Bel and all these birds were ringed at New Holme! For more information on the course please send an email to Megan Loftie-Eaton at megan@thebdi.org

Family Hyperoliidae
PAINTED REED FROG – Hyperolius marmoratus
Rapp, 1842
Habitat
H. marmoratus inhabits a variety of vegetation types within the Savanna, Grassland and Forest biomes, and occurs marginally in the Fynbos Biome. It is a widespread and abundant species along the coast and at low altitudes east of the Great Escarpment in Limpopo Province, Mpumalanga and Swaziland. However, large breeding populations are also recorded at higher elevations, e.g., 1300 m at Ixopo (3030AA) in the KwaZulu-Natal Midlands, and 1400 m at Haenertsburg (2329DD) in Limpopo Province. Jacobsen (1989) recorded this species in montane grassland at 1600 m.
H. marmoratus utilizes a wide variety of breeding sites, ranging from temporary ponds, pans and vleis, to permanent bodies of water such as dams, marshes, reedbeds, sluggish rivers and streams (Pienaar et al. 1976; Poynton and Broadley 1987; Lambiris 1989a; Channing 2001).
Behaviour
The adults aestivate during the dry season, and have been found sheltering some distance from their breeding sites in vegetation or under logs and stones. During this time they often take up residence inside houses, where they conceal themselves behind cupboards, pelmets, pictures and in toilet cisterns. The breeding behaviour of this species is arguably the best documented for any African frog, with more than 15 papers and numerous theses relating to the subject published within the last decade.
Although males will call after rain at any time of the year, breeding normally takes place October–February. At low altitudes male calling behaviour is inhibited by temperatures <16°C, while at higher altitudes breeding has been observed at temperatures <10°C (pers. obs.).
Hyperolius marmoratus – Calling male Palmiet Nature Reserve, KawZulu-Natal Photo by Nick Evans
Before dawn, breeding adults usually move into the canopy of surrounding trees or bask in the sun on emergent vegetation at the edge of the breeding site (pers. obs.). At dusk they descend to the water body where males take up specific call sites (to which they return on consecutive nights) and call consistently from dusk to just after midnight. Males occasionally call from their resting places in tree canopies in the late afternoon. Where present, tall emergent plants such as reeds and sedges (e.g., Eleocharis limosa, Cyperus papyrus and Typha capensis) are favoured as call sites, but males will also call from trees, grasses, bushes, floating vegetation or even bare soil at the water’s edge (L.R. Minter pers. comm.; pers. obs.).
On average, males call for only a few nights in a row, returning to the breeding chorus after a period of about 10 days (Dyson et al. 1992). Gravid females enter the pond shortly after dusk and usually select a mate within a few hours. After several hours in axillary amplexus, the eggs are laid in water. Females have been observed to lay more than one clutch of eggs per season with a month-long interval between layings (pers. obs.). From 150 to 650 eggs are laid in flattened clumps of c.20, on the surface of submerged leaves, stalks or stones, or amongst the roots of aquatic plants (Pienaar et al. 1976; Channing 2001). Tadpoles hatch within five days and metamorphosis takes 6–8 weeks (Pienaar et al. 1967). Males reach sexual maturity at approximately one year (A. Turner pers. comm.)
Predators include various birds, snakes, young crocodiles, terrapins, spiders and other frogs, while prey consists mainly of insects (Channing 2001; pers. obs.).
Status and Conservation
The major threat to this species is habitat loss through drainage of wetlands and afforestation. In several areas in KwaZulu-Natal, the establishment of exotic Eucalyptus plantations has lowered the water table to such a degree that many pans within the coastal dune forest have completely disappeared (pers. obs.).
H. marmoratus is widespread and locally abundant, and populations often consist of hundreds or even thousands of individuals. Atlas data indicate that the range of the species may be expanding. The species occurs in several national parks and numerous provincial nature reserves and therefore does not require additional conservation attention.
This species forms part of a large complex of geographical variants (subspecies), distributed across most of sub-Saharan Africa, which are distinguished from one another by differences in dorsal colour patterns. However, adjacent populations with different colour patterns often intergrade to a greater or lesser extent, while within populations themselves, there is variation in the colour and markings of juveniles and adult males. These factors, combined with a scarcity of behavioural and other data, have resulted in a confused and unresolved taxonomy (Poynton 1964, 1985; Schiøtz 1971, 1975, 1999; Pienaar et al. 1976; Poynton and Broadley 1987; Lambiris 1989a; Passmore and Carruthers 1995; Channing 2001). Ongoing investigation of the ecology, advertisement call structure and genetics of populations from different parts of Africa has already revealed the presence of cryptic species, and is gradually unravelling the systematics and stabilising the taxonomy of this complex (Channing 2001).
Schiøtz (1971, 1999) and Pienaar et al. (1976) assigned H. marmoratus to the superspecies H. viridiflavus, but other authors (Poynton 1985; Poynton and Broadley 1987; Lambiris 1989a; Passmore and Carruthers 1995) continue to recognise H. marmoratus as a separate species composed of a number of subspecies, or a species complex including several subspecies (Channing 2001). The latter approach is adopted here, pending a more thorough taxonomic and systematic revision of the complex.
Channing (2001) listed 13 subspecies of H. marmoratus distributed through sub-Saharan Africa, of which three occur in the atlas region. H. m. taeniatus is distributed from Limpopo Province, Mpumalanga and Swaziland, southward to about St Lucia (2832AD), where it intergrades with H. m. marmoratus (Lambiris 1989a). The latter occurs from St Lucia southward to west of Port Edward (3130AA), while H. m. verrucosus is recorded from the south coast of KwaZulu-Natal, southward along the Eastern Cape coast to Tsitsikamma (3323DD) in the Western Cape (Lambiris 1989a; Passmore and Carruthers 1995). There is currently no evidence to suggest that cryptic species are represented within these subspecies of H. marmoratus.
In recent years, several populations of H. marmoratus have been recorded further west of Tsitsikamma, through Swellendam (3420AB), to the Cape Peninsula (3418AB). While these new records may reflect a natural range extension, it is more likely that they have resulted from accidental or deliberate human-assisted translocations. Also, some of the westerly records in Limpopo, Gauteng and Mpumalanga provinces may be the result of translocations. For example, specimens of H. m.taeniatus have been encountered in consignments of bananas arriving in Cape Town from KwaZulu-Natal or Mpumalanga (A. de Villiers pers. comm.) and have been found in Pretoria on nursery plants originating from KwaZulu-Natal. A well-established population in Tokai on the Cape Peninsula (3418AB) is likely to have originated from such translocated animals.
This species has a loud, distinctive call and forms large choruses that are active for an extended period during the breeding season. The atlas data are reasonably complete and reliable.

Distribution
The Cape Bulbul is Endemic to South Africa. It is very common across much of the Western Cape, with its range extending along the coast to the Northern and Eastern Cape Provinces. The blue and green squares in the map below, which displays distribution data as captured by the second Southern African Bird Atlas Project (SABAP2), shows the core of the Cape Bulbul’s range. These are the squares where reporting rates for Cape Bulbul are highest.
SABAP2 distribution map for Cape Bulbul, downloaded on 30 March 2022. Details on how to interpret the map can be found here.
Behaviour
It is a locally common and conspicuous bird. They tend to perch at the top of a bushes making themselves easy to spot. Cape Bulbuls are active and noisy, and usually seen in pairs or small groups while foraging for fruit, nectar, and insects.

During the breeding season (September to December) the female builds the nest which consists of a sturdy but messy cup of twigs, grass stems and rootlets. The nest is typically placed on a horizontal branch near the edge of a bush’s or tree’s foliage. Cape Bulbuls lay 2-5 eggs, which are incubated solely by the female for about 11-13 days. Both parents feed the chicks, who remain dependent on their parents for food for a period of about 50 days from hatching.

The Spotted Eagle-Owl is a medium-sized, grey-brown owl with conspicuous ear-tufts and beautiful yellow eyes. The facial disk is off white to pale ochre in colour with a black outer edge. The upper body is dusky brown in colour with dark splotches on the breast while the lower parts are off-white with brown barring. Females and males are alike in colour and size.
Main photo: BirdPix 56614 – Zenobia van Dyk, Graafwater, Western Cape, 11 June 2016. Inset photo: BirdPix 18419 – Vaughan Jessnitz, Namoobspruit, Limpopo, 15 April 2015.
The juvenile birds resemble the adults, but their ear tufts are less distinct and they often still have some visible fluffy down feathers.
The call of Spotted Eagle-Owls is a mellow hoot. The males usually give a double hoot, ‘hoo-hooooee’, which the female answers with a softer triple hoot, ‘hoo-hoo-hooee’. Owls call to find partners, to tell their partners where they are and to proclaim their territories.
The Spotted Eagle-Owl can be confused with the Cape Eagle-Owl Bubo capensis. In general, Cape Eagle-Owls are more rufous-brown in colour rather than grey and they have orange eyes rather than yellow, but this is not always so obvious. The surest way to tell the two apart is by looking at the patterning on the breast. The Spotted Eagle-Owl has fine barring and greyish-brown splotches, while the Cape Eagle-Owl has black and chestnut blotching.
Habitat
Spotted Eagle-Owls occur in various habitats including woodlands, savannas and grasslands, shrublands, semi-deserts and rocky hills. They have adapted to living with people and are found in towns and cities, as long as there are gardens and parks where they can hunt at night and roost, undisturbed, during the day. They nest on or in buildings, on window ledges, or in owl boxes provided by people, and use streetlights and telephone poles as perches.

Distribution
Spotted Eagle-Owls are one of the most common owl species in southern Africa. They are often seen in Kirstenbosch National Botanical Garden in Cape Town. Its range extends across sub-Equatorial Africa to southern Arabia.
Data from the second Southern African Bird Atlas Project (SABAP2) shows that the Spotted Eagle-Owl occurs right across South Africa. There are lots of gaps in this distribution map because the citizen scientists who do the fieldwork for the atlas project are active by day, whereas the Spotted Eagle-Owls are active at night!
SABAP2 distribution map for Spotted Eagle-Owl, downloaded on 29 March 2022. Details on how to interpret the map can be found here.
Behaviour
The Spotted Eagle Owl is mostly active at night and before sunset. During the day it roosts in trees, or sheltered sites along cliff ledges, under bushes, abandoned buildings, or in burrows of other animals. When roosting in trees, it will usually sit close to the trunk with its feathers compressed, eyes closed, and ear-tufts erect. Breeding pairs will sometimes roost together, engaging in billing and allopreening.
They nest in many different places, most commonly on the ground, among rocks, under shrubs, in trees, tree hollows, cliff ledges, quarries, man-made structures, or eroded banks of a donga or river.
Chicks in the nest: BirdPix 21233 – Gregg Darling, St Francis Bay, Eastern Cape, 17 October 2015. Adult on its nest on the edge of a cliff: BirdPix 59624 – PR Kleinman, Underberg, KwaZulu-Natal, 31 August 2018.
They mate for life and usually lay two to three white eggs at intervals of between one to four days. The female incubates the eggs, while the male provides food. Chicks hatch blind and begin to open their distinct yellow eyes after seven days. The young start leaving the nest and exploring at about four to six weeks. The parents continue to care for the young for a another five or six weeks after they fledge.
Spotted Eagle-Owls have a varied diet. What they eat depends a lot on their habitat and what is available. They hunt at dusk and at night. They prey on insects such as crickets and large beetles, small mammals such as shrews, mice, rats, and squirrels, and birds up to the size of a Laughing Dove. They will also hunt and eat amphibians and reptiles.
