Rare birds in Slovenia in 2017 –Slovenian Rarities Committee's Report

Summary This report by the Slovenian Rarities Committee presents records of rare bird species in Slovenia in 2017, with some addenda for previous years. The numbers in brackets refer to the number of records (first number) and individuals (second number) recorded between 1 Jan 1950 and 31 Dec 2016. Since 1 Jan 2013, submission to the Committee has been required for 37 additional species, 17 of which are regional rarities. Records of these species are not numbered, since records from previous years were not collected by the Committee. The Barnacle Goose Branta leucopsis was first recorded in Category A, in addition to previous Category D and E records. Other notable observations were the third record of Red-breasted Goose Branta ruficollis, fifth records of Lammergeier Gypaetus barbatus and Pomarine Skua Stercorarius pomarinus, and seventh records of Greater Blackbacked Gull Larus marinus and Red Phalarope Phalaropus fulicarius. The list of birds recorded in Slovenia (as of 31 Dec 2017) contains 390 species (375 in Category A, 6 in Category B, 9 exclusively in Category C; 4 species are both in Categories A and C). Category D contains 7 species, while Category E contains 39, two of which are classified into Subcategory E*. These two categories are not part of the list.

This report by the Slovenian Rarities Committee presents records of rare bird species in Slovenia in 2014, with some addenda for previous years. The numbers in brackets refer to the number of records (first number) and individuals (second number) recorded between 1 Jan 1950 and 31 Dec 2013. Since 1 Jan 2013, submission to the Committee has been required for 37 additional species, 17 of which are regional rarities. Records of these species are not numbered, since records from previous years were not collected by the Committee. One new species was added to category C5: Sacred Ibis Threskiornis aethiopicus. One species, Spotted Dove Streptopelia chinensis, was added to category E. Breeding was confirmed for Muscovy Duck Cairina moschata and Northern Bobwhite Colinus virginianus; the two species were thus transferred to subcategory E*. Other notable observations were the third and fourth records of Black Vulture Aegypius monachus, fourth and fifth records of Gannet Morus bassanus, fourth record of Pomarine Skua Stercorarius pomarinus and fourth record of Richard’s Pipit Anthus richardi. The flocks of four Gannets and 23 Flamingos Phoenicopterus roseus have been the largest recorded in Slovenia to date. The list of birds recorded in Slovenia (as of 31 Dec 2014) contains 385 species (369 in category A, 7 in category B, 9 exclusively in category C; 4 species are both in categories A and C). Category D contains 6 species, while category E contains 34, two of which are classified into subcategory E*. These two categories are not part of the list.

The numbers in brackets refer to the number of records (first number) and individuals (second number) recorded between 1 Jan 1950 and 31 Dec 2014. Since 1 Jan 2013, submission to the Committee has been required for 37 additional species, 17 of which are regional rarities. Records of these species are not numbered, since records from previous years were not collected by the Committee. One new species, the Desert Wheatear Oenanthe deserti, was added to category A. Other notable observations were the first record of Parrot Crossbill Loxia pytyopsittacus after 1909, the second record of Baillon’s Crake Zapornia pusilla, the third and fourth records of Calandra Lark Melanocorypha calandra, the fourth of Long-legged Buzzard Buteo rufinus, the fifth of Richard’s Pipit Anthus richardi and the sixth of Grey Phalarope Phalaropus fulicarius. Four species were added to category E: Bahama Pintail Anas bahamensis, Rosy-billed Pochard Netta peposaca, Harris’s Hawk Parabuteo unicinctus and Alexandrine Parakeet Psittacula eupatria. The list of birds recorded in Slovenia (as of 31 Dec 2015) contains 386 species (371 in category A, 6 in category B, 9 exclusively in category C; 4 species are both in categories A and C).

Principal Actions

Considerable resources and efforts have been directed at biodiversity conservation in recent years, but measures of the success of conservation programmes have been limited. Based on information on population sizes, trends, threatening processes and the nature and intensity of conservation actions implemented during 1994–2004, we assessed that 16 bird species would have probably become extinct during this period if conservation programmes for them had not been undertaken. The mean minimum population size of these 16 species increased from 34 to 147 breeding individuals during 1994–2004. In 1994, 63% of them had declining populations but by 2004, 81% were increasing. Most of these species (63%) are found on islands. The principal threats that led to their decline were habitat loss and degradation (88%), invasive species (50%) and exploitation (38%), a pattern similar to that for other threatened species, but with exploitation and invasive species being relatively more important. The principal actions carried out were habitat protection and management (75% of species), control of invasive species (50%), and captive breeding and release (33%). The 16 species represent only 8.9% of those currently classified as Critically Endangered, and 1.3% of those threatened with extinction. Many of these additional species slipped closer to extinction during 1994–2004, including 164 that deteriorated in status sufficiently to be uplisted to higher categories of extinction risk on the IUCN Red List (IUCN, 2006). Efforts need to be considerably scaled up to prevent many more extinctions in the coming decades. The knowledge and tools to achieve this are available, but we need to mobilize the resources and political will to apply them.

Bird Distributions ◽

Open Country

We studied bird distributions on 15 small patches of subtropical rainforest, ranging from 0.08 to 2.5 ha, in north-eastern New South Wales. Three-quarters of the bird species found in an extensive area of nearby rainforest were recorded in one or more of these isolated patches. Species that were not recorded, generally were rare in the extensive forest or are characterized by large home ranges. Several species more typical of open country were also found in the isolated patches. The number of resident species per patch ranged from one to 19; these were added in a rather predictable order from small to larger areas. Additional species observed in the patches either were transient or had home ranges encompassing several discontinuous areas. Although area is the best single predictor of species richness, isolation, disturbance by livestock and distance from water all tend to reduce the number of resident bird species. We propose that high dispersal abilities of rainforest birds near Dorrigo reflect the geographical and palaeogeographical distribution of Australian rainforest. The small total area and discontinuity of original tracts of rainforest, perhaps accentuated during the Pleistocene, have generally prevented persistence or colonization of highly sedentary, specialized bird species.
