Diet of three sympatric species of granivorous songbirds in a Norwegian high mountain area during the early breeding season
Byrkjedal, Ingvar; Fjeldheim, Vegard Bang; Halvorsen, Lene Synnøve; Lislevand, Terje (Journal article; Peer reviewed, 2022)Stomach samples of Lapland Longspur Calcarius lapponicus, Snow Bunting Plectrophenax nivalis, and Horned Lark Eremophila alpestris were collected at Hardangervidda in an early phase of the breeding season (during egg-laying ... -
Eggsamlinger, rovfugler og miljøgifter
Lislevand, Terje (Årbok for Universitetsmuseet i Bergen;26, Chapter, 2021-12)At hunner legger egg, er vanlig i mange dyregrupper, men fuglene er unike ved at de beskytter innholdet i egget med et hardt, kalkrikt skall. Dette skallet er fra naturens side særdeles variabelt mellom arter, både i ... -
First records of complete annual cycles in water rails Rallus aquaticus show evidence of itinerant breeding and a complex migration system
Lislevand, Terje; Hahn, Steffen; Rislaa, Sven; Briedis, Martins (Journal article; Peer reviewed, 2020)In water rails Rallus aquaticus, northern and eastern populations are migratory while southern and western populations are sedentary. Few details are known about the annual cycle of this elusive species. We studied movements ... -
Incubation behaviour of the Common Ringed Plover Charadrius hiaticula at different latitudes
Wanders, Kees; Almalki, Mohammed; Heggøy, Oddvar; Lislevand, Terje; McGuigan, Chris; Eichhorn, Götz; Gabrielsen, Geir W.; Azarov, Viktoria; Khasyanova, Leylya; Székely, Tamás (Journal article; Peer reviewed, 2023)In biparental Charadriinae plovers, male and female incubation duties often resemble daily routines, with males typically incubating at night and females incubating during the day. By analysing incubation behaviour in three ... -
Limited male incubation ability and the evolution of egg size in shorebirds
Lislevand, Terje; Thomas, Gavin H. (Peer reviewed; Journal article, 2006-06-22)In bird species where males incubate but are smaller than females, egg size may be constrained by male body size, and hence ability to incubate the eggs. Using data from 71 such shorebird species, we show that egg size ... -
A long-term study of size variation in Northern Goshawk Accipiter gentilis across Scandinavia, with a focus on Norway
Walker, Samuel James; Lislevand, Terje; Meijer, Hanneke Johanna Maria (Journal article; Peer reviewed, 2023)Changing climate and growing human impacts are resulting in globally rising temperatures and the widespread loss of habitats. How species will adapt to these changes is not well understood. The Northern Goshawk (Accipiter ... -
Nest distribution and nest habitat of the Tibetan Partridge ( Perdix hodgsoniae ) near Lhasa, Tibet
Dorge, Tsering; Högstedt, Göran; Lislevand, Terje (Peer reviewed; Journal article, 2014-10-10)Background: Little is hitherto known about the breeding ecology of the Tibetan Partridge (Perdix hodgsoniae) which is endemic to the Tibetan plateau. Here we describe nest densities, inter-nest distances and general nest ... -

Red-spotted Bluethroats Luscinia s. svecica migrate along the Indo-European flyway: a geolocator study
Lislevand, Terje; Chutny, Bohumir; Byrkjedal, Ingvar; Pavel, Vaclav; Briedis, Martins; Adamik, Peter; Hahn, Steffen (Peer reviewed; Journal article, 2015-09-11)Capsule Red-spotted Bluethroats Luscinia s. svecica from two European breeding populations spent the boreal winter on the Indian sub-continent. Aim Tracking the migration of Red-spotted Bluethroats from Europe to the ... -
Selection of territorial habitat in a declining population of Lapland Longspurs Calcarius lapponicus
Fjeldheim, Vegard Bang; Byrkjedal, Ingvar; Lislevand, Terje (Journal article; Peer reviewed, 2023)The population of Lapland Longspur Calcarius lapponicus has declined drastically in the Scandinavian mountains over the last decades. One hypothesis is that the population decline has been caused by a change in vegetation ... -
Skipping-type migration in a small Arctic wader, the Temminck's stint Calidris temminckii
Lislevand, Terje; Hahn, Steffen (Peer reviewed; Journal article, 2015-03)By using morphometric data and geolocator tracking we investigated fuel loads and spatio-temporal patterns of migration and non-breeding in Temminck's stints Calidris temminckii. Body masses in stints captured at autumn ...
