转自:劳动午报 在一处偏僻田埂旁,一个不起眼的废弃快递单,成为揭开一张庞大犯罪网络的关键线索。辽宁大连警方 由此入手,与犯罪分子展开智斗,侦破一起涉案金额高达3900余万元的非法猎捕、收购、贩卖国家一级 保护野生动物大案,现场解救一大批黄胸鹀。 震惊:一张快递单背后,惊现黄胸鹀 "听说数量庞大,我们简直不敢相信自己的耳朵。"大连护鸟志愿者王大鹏回忆道。黄胸鹀在野外已难觅 踪迹,近年来数量虽有增加,但即便观测到十几只,都足以让志愿者们欣喜若狂。 (来源:劳动午报) 案件背后,是一场侦查与反侦查的无声较量。 "没想到规模这么大。"全程参与案件侦办的大连市公安局环食药支队民警杨东鹏坦言。黄胸鹀曾是北方 田野常见的"禾花雀",因栖息地破坏与人为捕猎,种群数量断崖式下降,已被世界自然保护联盟列为极 度濒危物种,我国于2021年将黄胸鹀保护级别提升至国家一级。 犯罪嫌疑人盯上的恰是这种濒危物种。快递单上的收件人信息模糊、物品名隐晦,出现地点也颇为偏 僻。结合季节性作案特点,民警判断背后极可能存在非法狩猎活动。 经过缜密侦查,一个以张某某、姜某为核心的猎捕、收购、圈养、贩卖网络逐渐浮现。今年9月28日, 警方在黄胸鹀迁徙过 ...

转自:北京日报客户端 隆冬时节,北京最低气温已跌破零摄氏度。 奥林匹克森林公园南园龙形水系的一角,却仍有一片水面尚未完全封冻。芦苇丛间,鸿雁、斑头雁、绿 头鸭、白骨顶鸡在水中游弋,时而振翅而起,在空中盘旋一圈又落回水面。 奥林匹克森林公园的鸿雁在水上嬉戏 每当群鸟起飞,快门声便此起彼伏。有人举着长焦镜头追随拍摄,也有人从兜里掏出玉米粒,抛向冰面 和水中。"这天寒地冻的,草都黄了,不喂它们真怕饿着。"常来公园观鸟的宋阿姨说。 这样鲜活的画面,如今正遍布北京的河湖湿地与城市公园,留鸟数量增多的变化,在各处都清晰可见。 密云太师屯镇的清水河畔,几十只天鹅齐聚河面,洁白的身姿在粼粼水波间舒展,相较往年,天鹅越冬 的数量与停留时长都有所增加;碧波荡漾的密云水库,更是成了珍稀鸟类的越冬乐园,中华秋沙鸭、斑 头秋沙鸭在水面灵活穿梭捕鱼,红隼盘旋于上空守护领地;亦庄调节池里,数十只普通秋沙鸭、白秋沙 鸭结伴游弋,与绿头鸭、小鸊鷉相映成趣。 有着十多年观察鸟类经验的潘清泉告诉记者,按照以往规律,冬候鸟一般会在冬至前完成迁徙,"但现 在,越来越多'天一冷就走'的候鸟,选择留在北京过冬"。 不南飞了如何过冬? 自主觅食外还有"固定 ...

看到视频的宋大昭难掩激动。"阜平监测到华北豹,意味着华北豹离北京又近了一步。" 阜平县林业局局长杨建伟告诉北青报记者,近期红外相机拍摄到的画面,是近十年来太行山脉河北段记录到的最北位置的华北豹个体,其活动地点距 北京市直线距离仅约160公里,具有重要的区域生态指示价值。 全身覆着独特黑色斑纹的华北豹,悄然现身河北阜平群山间,此地距北京仅160公里。只见它矫健地攀至高处,环视四周,随即敏捷转身,没入幽深 密林。这一幕被红外相机清晰捕捉,令长期致力于"迎豹回家"的公益组织猫盟创始人宋大昭难抑激动——这意味着,在北京消失30年的华北豹,回家之路 又近了一步。 华北豹是生物多样性保护的重要指示物种,对维持生态平衡发挥着巨大作用。北京青年报记者了解到,2024年起,猫盟、清华大学与河北省各级林业 部门组建了联合团队,在阜平县开展大量的监测工作,终于在今年确认有野生华北豹在此栖息,为"迎豹回家"计划找到了关键跳板。 野生华北豹的稳定栖息,离不开适宜的生存环境。目前,京冀晋多地力量正在共同努力,打造有利于华北豹及其他野生动物生存繁衍的森林环境。推 动森林不但要绿起来,更要"活"起来,已成为各方共识。 华北豹"惊现"河北阜平 ...
