摘要

本文描述了2008年4月至2023年1月期间在布隆方丹西南Jagersfontein路2915_2555 Pentad进行的鸟类调查结果。共记录了197个物种,主要来自169个完整协议SABAP2卡(162个由作者完成)和30多个临时列表。根据雨季过后水鸟的反应和出现情况,讨论了水鸟的季节性。黄嘴鸭(49.7%)、红嘴鸭(37.9%)和白面啸鸭(32.0%)在夏季的报告率较高,有时在干燥的冬季仍会出现。刺翅鹅(39.6%)和埃及鹅(69.2%)也有较高的报告发病率,尽管南非野鸭的季节性发病率较低(17.8%)。讨论了燕尾蜂和镰翅蜂等冬候鸟的季节特征。4 - 8月间,镰状翼闲聊主要分布在草地开阔斑块和砾石路面的低矮灌木上。5月至7月在Praalhoek农场山坡上的budleja sp.灌木区观察到燕尾蜂食虫。此外,还讨论了夏初雨后开始鸣唱的云雀的季节分布。通过SABAP2项目(以及其他平台,如虚拟博物馆数字化项目)对鸟类种群的持续监测得到了强调,因此随着时间的推移监测鸟类种群的重要性。

Birds of SABAP2 pentad 2915_2555 on the Jagersfontein Road, south-west of Bloemfontein, Free State
This paper describes results of a bird survey done at Pentad 2915_2555 on the Jagersfontein road south-west of Bloemfontein between April 2008 and January 2023.  A total of 197 species have been recorded from mainly 169 full-protocol SABAP2 cards (162 done by author) and more than 30 ad hoc lists. The seasonality of waterbird species is discussed based on responses and occurrences after the rainfall seasons. Higher reporting rates were obtained for species such as Yellow-billed Ducks (49.7%), Red-billed Teals (37.9%) and White-faced Whistling Ducks (32.0%) during the summer months, which were sometimes still present into the drier winter months. Spur-winged Goose (39.6%) and Egyptian Goose (69.2%) also have high reporting occurrences, although South African Shelducks showed a more seasonal occurrence with lower reporting rates (17.8%). The seasonality of winter visiting species such as Swallow-tailed Bee eater and Sickle-winged Chats is discussed. Sickle-winged Chats were mostly observed in the area between April–August preferring low shrubs in open patches in grassland and on gravel roads.  Swallow-tailed Bee eater were observed in the Buddleja sp. bush areas on the slope of the hill at the Praalhoek farm between May and July.  The seasonal occurrence of Melodeuis Larks, which starts singing after the first summer rains, is also discussed. The ongoing monitoring of bird populations through the SABAP2 project (and with other platforms such as the Virtual Museum digitization projects) is emphasized and therefore the importance of monitoring bird populations over time.
