International Owl Society, September 2004.)
During 10 May - 2 June 2002, I explored 15 locations in Malawi and eastern
Zambia for owls. I used tapes of owl calls and my own vocalizations, and on
several nights set up a sound-activated cassette recorder to catch night
sounds. The sampling intensity (frequency and duration of calling and
listening, and number of days and nights) varied among sites, but I tried to
hold each calling station relatively constant at about 20 minutes each. Over
20 days and nights, I catalogued a total of 34 owls among 10 species,
including all species known to occur in Malawi and eastern Zambia except for
Pel's Fishing Owl. The following table summarizes my findings:

\1 Location codes
(all in Malawi unless noted otherwise): DZ = Dzalanyama Forest Reserve; LI =
Liwonde National Park & Shire River; ZO = Zomba Plateau and Forest Reserve;
NC = Nchalo, Chikawa; LE = Lengwe National Park; SA = Satemwa Tea Estate,
Thyolo Mountain & Escarpment, and Shire Highlands; SE = Senga Bay, Lake
Malawi; VI = Viphya Plateau; NY = Nyika Plateau & National Park; VW = Vwaza
Marsh Game Reserve; NK = Nkhotakhota Game Reserve; NJ = Njobvu, Lake Malawi;
NT = Ntchisi Forest Reserve; LU = Lupande Game Management Area, Zambia; SL =
South Luangwa National Park, Zambia.
Lack of detection of owls in specific locations should not be interpreted as
absence of the species there, given the low number of nights and hours spent
at each site. However, overall, the species I encountered most often was
Spotted Eagle Owl, followed by African Scops Owl and Giant Eagle Owl. The
species seen least often was White-faced Owl. The site having the highest
numbers and diversity of owls was SL (see above location codes) in eastern
Zambia where I saw 8 individual owls among 6 species. In Malawi, VW was
relatively owl-rich, with 6 owls sighted among 3 species. NY was the only
location where I saw Marsh Owl and Grass Owl, in the highland grasslands.
Owls that responded to my solicited calls (tape or voice) included African
Scops, African Barred, Wood, Pearl-spotted, and Marsh Owls. Other species
were chance encounters or did not specifically respond, although during
previous owling expeditions (June-July 2000) in South Africa, Zimbabwe, and
Caprivi Strip of Namibia, I also solicited active responses from Giant Eagle
and Spotted Eagle Owls.
I explicitly called for Cape Eagle Owl in several locations including DZ, LI,
and LE, but did not find any of this species.
I also spent a total of 36 hours searching expressly for Pel's Fishing Owl
(in all sites but intensively in LI, ZO, SE, SL, VW, and NJ) via hiking,
boating along Lake Malawi shorelines, and 4-wheel drives, during day,
evening, and night, at historic or known resting, foraging, roosting, and
nesting sites, accompanied by local guides who knew the locations. I heard
and saw no Pel's. This does not necessarily signal absence of the species,
but others might attempt further surveys to help determine long-term
presence.
