黑龙江嫩江高峰林区鸟类环志监测报告

1998～2006年,笔者在黑龙江省嫩江县高峰林场开展了鸟类环志研究工作。这里是候鸟经松嫩平原迁徙途中重要的停歇地和食物补给站。9年共环志鸟类13目37科165种184273只,其中春季135种80366只,秋季140种103907只。环志最多年份为2002年,44633只。环志数量最多的种类是白腰朱顶雀Cardueli sflammea,272日3只,其次是黄雀C.spinus,20163只。在所环志的鸟类中,春季以小鹀Emberiza pusilla、红胁蓝尾鸲Tarsiger cyanurus、黄眉柳莺Phyllosco pusinornatus、栗鹀E.rutila、田鹀E.rustica、黄眉鹀E.chrysophrys、燕雀Fringilla montifringilla、黄雀等8种为优势种:秋季以白腰朱顶雀、黄雀、田鹀、黄眉柳莺、燕雀、北朱雀Carpodacusroseus等6种为优势种,占秋季环志数量的69.3%。系统的环志监测,为深入开展鸟类环志研究,探索鸟类迁徙规律,以及进行鸟类疫情监测提供更为可靠的数据。     

嫩江高峰林区鸟类迁徙与气象因子的相关性初探

2001～2010年在黑龙江省嫩江县高峰林场开展了鸟类环志研究工作,共环志鸟类173种238672只,其中春季142种102285只,秋季147种136387只,隶属14目41科。春季以小鹀Emberiza pusilla、红胁蓝尾鸲Tar-siger cyanurus、黄眉柳莺Phylloscopus inornatus、栗鹀E.rutila、黄眉鹀E.chrysophrys、燕雀Fringilla montifringilla、田鹀E.rustica、黄雀Carduelis spinus等8种为迁徙鸟类的优势种,累计75145只,占春季环志数量的73.5%;秋季以白腰朱顶雀Carduelis flammea、黄雀、田鹀、燕雀、黄眉柳莺、煤山雀Parus ater、北朱雀Carpodacus roseus等7种为迁徙鸟类的优势种,累计99335只,占秋季环志数量的72.8%。利用统计软件对气象因子中的平均气温、日最高气温、日最低气温、平均水汽压、日最低气压、日最高气压、相对湿度、地面平均温度、平均风速、最大风速、最大风速的风向、日照时数与春秋季迁徙鸟类的优势种的相关性进行了分析,发现地面平均温度、日最高气温与鸟类迁徙的相关性很强。在春季,与鸟类迁徙的相关性很强的还有日最高气压,而秋季则是日照时数。相对湿度在鸟类迁徙中呈很强的负相关。     

吉林珲春2002～2005年鸟类环志监测报告

2002～2005年在吉林省珲春市马川子乡依力南沟开展了鸟类环志研究工作。这里为长白山低山丘陵区,是候鸟经长白山脉、乌苏里江迁徙途中重要的停歇地和食物补给站。4年共环志鸟类126种63386只,其中春季103种9761只,秋季113种53625只,隶属13目37科。春季以黄喉鸦（Emberiza elegans）为迁徙鸟类的优势种,环志2467只,占春季环志数量的25．3％;秋季以黄喉鸦、红胁蓝尾鸲（Tarsiger cyanurus）、黄眉柳莺（Phylloscopus inornatus）、大山雀（Parus major）、白眉鸦（E.tristrami）、极北柳莺（P.borealis）等6种为迁徙鸟类的优势种,累计33586只,占秋季环志数量的62．6％;通过环志研究发现,被认为是留鸟的大山雀、银喉长尾山雀（Aeghhalos caudatus）、沼泽山雀（P.palustris）、长尾雀（Uragus sibiricus）具有定期的迁徙行为。     

嫩江高峰林区白腰朱顶雀的环志回收

高峰鸟类保护环志站地处大、小兴安岭之间的嫩江河谷东岸,松嫩平原北麓。特殊的地理位置使这里成为候鸟经松嫩平原迁徙途中重要的停歇地和食物补给站。自1998年开展环志以来,截止2005年12月末,在该地区发现鸟类210种,隶属15目36科,环志鸟类163种163305只,其中,白腰朱顶雀(Carduelis flammea)环志26157只,是高峰鸟类保护环志站环志数量最多的种类。2003年2月10日挪威回收到由高峰鸟类保护环志站环志的一只白腰朱顶雀,成为中国开展鸟类环志20多年来,欧洲国家回收到的第一只中国环志鸟。之后,在俄罗斯、荷兰也相继回收到高峰环志的鸟类,使高峰鸟类保护环志工作再度引起鸟类学家的关注。     

哀牢山北段大中山候鸟聚集地秋季夜间迁徙鸟类多样性

环志是研究迁徙鸟类的重要途径。云南省哀牢山北段大中山是鸟类迁徙的重要通道,但缺乏具体的研究数据。1997年、2010年和2011年秋季夜间迁徙鸟类环志研究的结果表明,哀牢山北段大中山捕获到的夜间鸟类有108种2330只,分属10目24科。其中,以雀形目鸟类为主,占总捕获数量的78.3%,捕获优势种为树鹨(占捕获数量的16.95%)、红喉姬鹟(13.39%)、红尾伯劳(9.83%)、红喉歌鸲(8.71%)和栗鹀(4.80%);水禽占捕获鸟类总种数的16.7%,与云南其他地点的研究结果相似。由于水禽是传播禽流感的主要载体,候鸟聚集地存在传播禽流感的风险,春季也有候鸟翻越哀牢山,因此有必要开展春季鸟类环志工作。     

近10年秦皇岛两种鸟类春季迁徙 时间变化的差异性

气候变化对鸟类迁徙时间的影响是目前生态学研究的热点问题。本文利用鸟类环志的方法分析了2010至2019年河北秦皇岛两种鸟类春季迁徙时间变化趋势及其差异性,并进一步探讨了差异性的原因。选择环志数量较多的食虫鸟黄眉柳莺(Phylloscopus inornatus)和食谷鸟灰头鹀(Emberiza spodocephala)作为研究对象,分析了10年间两种鸟类春季迁徙到达时间、高峰期、离开时间和停歇天数的变化及其相关性。结果表明,10年间黄眉柳莺和灰头鹀春季迁徙到达时间、高峰期和离开时间都出现了提前现象。黄眉柳莺和灰头鹀在秦皇岛停歇天数都呈现缩短的趋势,黄眉柳莺到达时间与离开时间存在显著的正相关。两种候鸟春季迁徙时间出现这种变化的原因是由于秦皇岛环境温度呈现逐渐升高的趋势,促使各种植被群落和昆虫提前进入生长繁殖阶段,为春季提前迁徙而来的候鸟提供丰富的食物资源。黄眉柳莺春季迁徙期在秦皇岛采取“早到早走”的策略,提早到达繁殖地可以增加其繁殖成功率,有助于提高鸟类种群的生存率。     

中国东北地区基于环志监测的田鹀迁徙趋势和数量动态北大核心CSCD

许多长距离迁徙的雀形目鸟类的种群数量正在持续下降,田鹀(Emberiza rustica)种群数量下降趋势更为突出。通过对田鹀种群数量长期监测和迁徙动态分析,可为此物种保护提供科学依据。从2001年开始,陆续在黑龙江省高峰、青峰、帽儿山、新青和大沾河,吉林省珲春和吉林市,辽宁省的辽宁鸟类研究中心(大连)和旅顺老铁山,以及内蒙古乌尔其汗鸟类栖息的临水林缘处布网环志。截至2018年,累计环志田鹀184181只,其中春季88571只,秋季95610只;各年度环志数量波动较大,总体呈现急速下降趋势。幼鸟的越冬损失率高达41.3%。田鹀106只次的回收信息表明,自然条件下田鹀寿命可达11年以上;日迁飞距离最快可达到300 km,飞行速度可达30 km/h。中国东北地区是田鹀等鸟类的重要迁徙途经地;田鹀的迁徙路线相对稳定,在瑞典北部繁殖的种群经中国东北地区迁徙到天津以南越冬。通过环志发现,近些年田鹀种群数量急速下降。通过比对,发现中国东北地区田鹀的环志数量变化趋势与瑞典的田鹀环志数量变化趋势相似;相对于环志数量最多的年份,环志数量下降95%以上,值得关注。栖息地破碎化、非法猎捕等是影响田鹀生存的主要受威胁因素。建议依据田鹀等鸟类生物学习性,加强鸟类栖息地的保护,坚持长期标准化的鸟类环志监测,进一步探索鸟类迁徙规律,以助于鸟类种群的恢复。     

沈阳桃仙国际机场鸟类夜间迁徙规律

在鸟类迁徙季节,夜间鸟击事故频发是机场鸟击发生的一个显著特点.了解鸟类的夜间迁徙规律对于改进夜间鸟击防范措施具有重要的指导意义.本研究综合采用网捕法和声音记录法对沈阳桃仙机场夜间鸟类迁徙物种组成和迁徙规律进行研究.结果表明: 56种鸟类(占比88.9%)具有夜间迁徙习性,且以后半夜迁徙为主;鸟类夜间迁徙具有明显的时间动态和迁徙次序,春季鸟类迁徙较为集中,迁徙高峰在5月中旬,主要鸟类由鹌鹑、红尾伯劳、栗耳鹀、黑喉石鵖、普通夜鹰、黄眉柳莺等组成,秋季迁徙较为分散,迁徙高峰出现在9月下旬至10月上旬,主要由鹌鹑、灰背鸫、红喉鹨、丘鹬、矛斑蝗莺和灰头鵐等组成.对夜间迁徙鸟类的危险等级评估发现,春季严重危险物种是鹌鹑和红尾伯劳,秋季严重危险物种是鹌鹑、纵纹腹小鸮、灰背鸫和丘鹬.分别从夜间迁徙鸟类组成、迁徙动态、时间节律和物种危险等级等角度提出了相应的鸟击防范对策,为桃仙机场鸟击防范提供参考.     

2002年北戴河林栖迁徙鸟类环志

2002年4月1日～10月31日,共环志林栖迁徙鸟类7目、20科、84种12244只,环志数量超过100只的鸟有23种。春季性别鉴定16种1224只,雌雄比例约为1：1．1;秋季鉴定20种1656只,雌雄比例约为1．4：1。春秋两季大致3d一个迁徙高峰,春季的迁徙曲线高峰斜度较秋季的大,秋季的迁徙高峰比较平缓。     

盐城沿海海堤林带柳莺属(Phylloscopus)鸟类秋季迁徙规律

江苏盐城沿海具有广阔的平原与湿地滩涂,但缺少自然林地。经过多年的防风林建设,沿海海堤逐渐形成了特有的、南北走向的条带林生境,为迁徙鸟类提供了通道和停歇地,是研究鸟类迁徙规律的理想地点。柳莺属鸟类个体小,野外种类识别难,其迁徙规律缺乏深入研究。分别于2018年和2019年两个秋季,采用雾网法对盐城沿海海堤林带柳莺属鸟类的迁徙规律进行研究。结果表明：两个秋季共捕获柳莺属鸟类8种608只,其中极北柳莺（Phylloscopus borealis）、冕柳莺（P. coronatus）、淡脚柳莺（P. tenellipes）和黄眉柳莺（P. inornatus）的捕获数量分别为245只、131只、107只和94只,占捕获总数量的95%,是秋季迁徙期的优势种。对优势种柳莺日捕获率进行比较：2019年极北柳莺的日捕获率显著高于淡脚柳莺和黄眉柳莺（U test,P<0.05）。对捕获数量随时间变化进行分析,4种柳莺都以集中在短时间内快速通过的迁徙策略穿越盐城沿海海堤林带,符合秋季小型雀形目鸟类迁徙采取时间最小化假说。不同种类的柳莺在通过盐城沿海海堤林带的时间顺序上存在显著差异（K-W test,P<0.05）,2018年和2019年均以黄眉柳莺通过最晚。随着时间的推移,四种柳莺的脂肪度都逐渐下降。繁殖地纬度的差异可能是导致4种柳莺通过盐城沿海海堤林带时间差异的原因。盐城沿海海堤林带为柳莺属等雀形目小型鸟类的迁徙提供了非常理想的迁徙通道,应当加强海堤林带在鸟类迁徙和保护中的作用研究。     

Successful restoration of water level and surface area restored migrant bird populations in a Hungarian wetland

Water level and water surface area fluctuations are important factors determining abundance of bird populations and bird assemblages structure in a wetland habitat. The water level and water surface area of the Marsh T?m?rd (West Hungary) changed drastically between 1998 and 2008, and the marsh dried out because of scarce rainfall in 2000 and 2001. A habitat restoration in winter 2001 repaired the waterholding capacity of the marsh. We analyzed changes in parameters of bird assemblages in investigated wetland area in relation of environmental factors. We used full redundancy analysis (RDA) on number of caugth migratory birds per year, species richness, diversity and evenness of bird assemblages to examine correlations among water level, water surface area and vegetation core. Species like water rail, common snipe, river warbler, Savi’s warbler, great reed warbler, reed warbler, marsh warbler, sedge warbler, reed bunting showed high and positive linear correlations with the water level and water surface area in the postbreeding period. Some wetland species, sedge warbler, Savi’s warbler and reed bunting as well as total number of caugth birds per year and total numbers of caugth species per year were clearly associated with thick marsh vegetation. According to our results the bird species composition of the wetland might have returned to the prerestoration levels and surface areas.     

A survey for Yersinia pseudotuberculosis in migratory birds in coastal Japan

Yersinia pseudotuberculosis was isolated from three specimens of two species of birds, the black-faced bunting (Emberiza spodocephala) and pied wagtail (Motacilla alba), of 528 specimens of birds examined from coastal regions in Japan. The two isolated strains of Y. pseudotuberculosis were identified as serovar 4b and serovar 3. This is the first isolation of Y. pseudotuberculosis from birds in Japan. Yersinia enterocolitica was isolated from three specimens of the pied wagtail, one specimen of the reed bunting (Emberiza schoeniclus) and one specimen of the rustic bunting (Emberiza rustica). Yersinia frederiksenii was isolated from two specimens of the gray-rumped sandpiper (Heteroscelus brevipes). Yersinia intermedia was isolated from one specimen of the pied wagtail.     

鸟市贸易威胁野生鸟类生存——以哈尔滨道外花鸟鱼市场为例

为探讨鸟市贸易对野生鸟类的威胁与影响,给当地野生动物保护部门实施监管提供科学依据,于2016年11月—2017年11月对黑龙江省哈尔滨市最大鸟市——道外花鸟鱼市场进行调查。结果发现:(1)共记录6目34科83属117种18 729只鸟类,其中野生鸟类5目32科77属108种11 662只。有出售国家保护鸟种黄胸鹀 Emberiza aureola、猛禽及非法捕猎工具的现象。(2)所有被贩卖的野生鸟类中,在黑龙江省有分布的共69种,数量达9 707只。相关分析结果表明,黑龙江省有分布的野生鸟类是鸟市非法捕捉及贩卖的主要对象。(3)贩卖量为春、秋季多,夏、冬季少,7—10月鸟类迁徙季节时最多,占总贩卖量的45.2%,说明鸟类秋季迁徙是非法猎捕的高峰期。(4)调查中发现较多的南方鸟种(32.4%)也一定程度上说明野生鸟类非法运输的严重性。建议当地林业和草原局及时加强对道外花鸟鱼市场的监管,在鸟类迁徙季节从非法捕捉和运输环节实施严厉打击。     

中国四种小型鸟类代谢产热的气候适应

采用封闭式流体压力呼吸计 ,分别在 5 - 35°C、 10 - 30°C和 10 - 35°C的环境温度范围内测定了黄眉(Emberizachrysophrys)、红胁绣眼鸟 (Zosteropserythropleura)、画眉 (Garrulaxcanorus)和红嘴相思鸟 (Leio thrixlutea)的耗氧量、热传导、体温等指标 ,探讨了其代谢产热特征。黄眉、红胁绣眼鸟、画眉和红嘴相思鸟的热中性区分别为 2 5 - 30°C、 2 5 - 2 7 5°C、 2 2 5 - 2 7 5°C和 30 - 32 5°C。在 5 - 30°C的温度范围内 ,黄眉和画眉能保持稳定的体温 ,分别为 4 0 5 8± 0 2 6°C和 4 1 6 8± 0 11°C ;红胁绣眼鸟和红嘴相思鸟的体温随环境温度的降低有下降的趋势。在热中性区内 ,黄眉、红胁绣眼鸟、画眉和红嘴相思鸟的平均基础代谢率分别是3 6 5± 0 14、 4 6 9± 0 2 7、 3 5 5± 0 14和 4 2 4± 0 17mlO2 / (g·h) ,分别是体重预期值的 12 8%、 2 30 %、 6 0 %和 12 0 %。在下临界温度以下 ,黄眉、红胁绣眼鸟、画眉和红嘴相思鸟的最小热传导分别是 0 2 4、 0 31、 0 2 1和 0 34mlO2 / (g·h·°C) ,分别是体重预期值的 14 9%、 14 9%、 2 15 %和 2 4 3%。这些小型鸟类的生理生态学特征是 :(1)黄眉和红胁绣眼鸟有高的基础代谢率和相对低的下临界温度 ,适应低温环境     

广东鹤山丘陵人工林林下鸟群落研究

2003年5月到2004年4月,在鹤山人工林中张网6353网小时,捕到林下鸟28种110只,平均网捕率为1.73只/100网h。其中冬候鸟的种类和数量分别占整个网捕鸟种类和数量的42.86%和33.64%。优势种是大山雀(P arusm ajor)、白头鹎(Py cnonotus sinensis)和红胁蓝尾鸲(T arsig er cyanurus)。鹤山20a林龄的人工林林下鸟群落具有:种类和数量贫乏、网捕率低、画眉科的鸟少等特点。林下鸟群落的种类、数量、组成和网捕率与植被有关,相思林种类最丰富、网捕率最高;针叶林种类最少、网捕率最低;4种植被类型中林下鸟种类和网捕率大小排序是:相思林>荷木林>桉树林>针叶林。相思林与荷木林有最大的种的相似性(0.43)、而相思林与针叶林种的相似性最小(0.20)。林下鸟丰度和网捕率均存在季节变化,冬季种类最丰富、春季次之、而夏季和秋季种类最少。在针叶林(F3,44=4.514,p<0.01)和荷木林中(F3,44=4.449,p<0.01),林下鸟的网捕率有极显著的季节变化,冬季的网捕率最高、夏季的网捕率最低;而在相思林(F3,44=1.893,p>0.05)和桉树林中(F3,44=1.212,p>0.05),林下鸟的网捕率季节差异不显著。     

Territoriality,philopatry, and nest-site fidelity in robins trapped in Moscow oblast

From 1999 to 2005 at Zvenigorod Biological Station (Moscow oblast, Russia, 55°44′N, 36°51′E) field studies were performed. Birds were trapped using mist-nets. The Russian Ringing Center provided data collected from 1948 on robins captured outside the Moscow oblast. A total of 5751 robins were trapped and banded in the Moscow oblast. Only two birds (0.03%) were retrapped the following years. Three birds banded in the Moscow oblast were found in other regions. In addition, two robins banded in other countries were caught at Zvenigorod Biological Station. The rate of long-distance recoveries was 0.09%. The Russian Ringing Center reports on three robins banded in other countries and found in the Moscow oblast, and one robin banded in the Moscow oblast and then found in a different country. It was shown that robins born or breed in the Moscow oblast exhibited neither nest-site fidelity nor natal homing, which is the case for other areas. Wintering grounds of robins born or breed in the Moscow oblast are located within a single zone (north-east of Spain, south of France and Italy). This area is also wintering ground for robins from other regions. There exists one route connecting the wintering grounds for robins with the Moscow oblast which birds follow during autumn and spring migrations. It is possible that the Moscow oblast is a nesting area for robins born or breed in the north of Russia (including Finland and the Leningrad oblast). Natal sites and nest sites of robins could be separated by a distance of 1000 km or more.     

Reedbed structure and habitat preference of reed passerines during the post-breeding period

Post-breeding habitats of nine passerine species were studied in the permanently flooded reed beds of ponds near the village Pusté úlany (SW Slovakia) in 2002. Structural features of reed beds and the abundance of all birds studied were sampled at two sites and eight study plots. The reed bed structure and abundance of four passerines differed considerably between the individual study plots. The variations in vegetation structure were also caused by winter reed burning in the SE part of study area. Stems in burnt reed beds were smaller and thinner than unburnt. Abundance of the reed warbler and to a lesser extent sedge warbler was higher in tall reed beds, while the bearded tit preferred thick reed stems. Position of reed beds along the shore — open water gradient was an important factor in terms of abundance at the study plots in the case of the reed bunting. This species showed a strong preference for the reed bed edge with open water. Horizontal distribution of other species seems to be random, however, the birds with the exception of Savi’s warbler preferred the upper stratum of reed bed in vertical distribution. Our field data corroborate with those found in experimental studies concerning with ecomorphological characteristics of birds. Some inconsistencies, however, could also be caused by other factors (e.g. foraging preferences). Comparison of breeding and post-breeding habitat requirements of the studied bird species confirmed a more or less random distribution of the majority of species in the post-breeding period. Some variation was found in the cases of only the reed warbler and bearded tit.     

Rapid 'evolution' of migratory behaviour in the introduced house finch of eastern North America

The house finch (Carpodacus mexicanus) of eastern North America was introduced onto Long Island, New York, around 1940. The source is presumed to be southern California, where ca. 80% of individuals are completely sedentary. The eastern population has become migratory: by the early 1960s, 36% of eastern house finches were performing migratory movements (more than 80 km from their banding site) and that proportion has fluctuated between 28% and 54% in succeeding years. The movements of birds banded during the breeding season and recovered in winter were strongly orientated toward the south-west, and the same pattern was evident in the earliest recoveries (1958 to 1966); recoveries of birds banded during winter and recovered in the breeding season were orientated toward the north-east. The average distance of migration has continued to increase logarithmically. Areas colonized later, as the range expanded, were characterized by initial long migration distances and high proportions of migrants, suggesting that these traits have evolved in the eastern population. Eastern house finches are partial migrants: not all individuals migrate, and birds that migrate some winters remain in breeding areas in others. Younger birds exhibit a stronger tendency to migrate. A very few western (including southern California) house finches moved long distances, but they did so in directions consistent with seasonal migration, indicating that the machinery subserving migratory behaviour pre-existed in the parent population.     

Viability of meta-populations of wetland birds in a fragmented landscape: testing the key-patch approach

The key patch approach assumes that metapopulations in fragmented landscapes are likely to be viable with at least one “key” sub-population that is sufficiently large to ensure re-colonization of surrounding minor habitat patches. It is based on a minimum viable number of breeding pairs and within-breeding season dispersal distance, linked to size of the animal and longevity. It was tested using census data of 15 wetland bird species (bearded tit, bluethroat, great reed warbler, sedge warbler, Savi’s warbler, grasshopper warbler, spotted crake, water rail, common snipe, common teal, garganey, little bittern, night heron, great bittern and marsh harrier) in 14 wetland complexes of variable size (3–55 km²) spread across the Netherlands (distances ranging 4–156 km). First, for each species it was assessed whether a wetland harbored a key subpopulation, which was the case for the sedge warbler (7 key subpopulations), grass-hopper warbler (2), water rail (2), bearded tit, bluethroat, Savi’s warbler, common teal, garganey, great bittern and marsh harrier (all one key subpopulation).Together with the adjacent sub-populations present within breeding season dispersal distance, 10 out of the 15 studied species formed viable meta-populations. This was compared with the trend in the census data of 13 species for 1990–2000 and was found to correspond significantly (likelihood ratio test, P = 0.003): species without a viable meta-population had declined (2 out of 4) or remained stable (2 out of 4), whereas viable meta-populations had increased (6 out of 9) or remained comparatively stable (2 out of 9). One wetland complex, the Oostvaardersplassen, stood out in that it haboured key sub-populations for 9 out of the 15 species studied. Variation in quantity of specific habitat (area or perimeter marshland, woodland or open water) in a wetland complex was of limited importance explaining abundance patterns, since all covaried strongly with total area among the wetland complexes, with the exception of water perimeter. Apparently, these wetlands on peat harbour largely similar landscapes. Indeed, population sizes of most birds covaried strongly and in a PCA two distinct clusters of species were identified that shared high numbers of breeding pairs in the same, larger, wetland complexes, the first (3 species) including the great reed warbler, and the second (9 species) the water rail.
