格日勒鸟（学名Gurilynia）是一属反鸟亚纲鸟类。^[1]其下只有G. nessovi一个物种。它们生存在白垩纪晚期的马斯垂克阶。^[2]格日勒鸟的化石只是碎片，都是在蒙古戈壁南部的耐梅盖特地层（Nemegt Formation）发现。

格日勒鸟的化石包括三个骨头部份。完模标本是右肱骨的近端部份，编号PIN 4499-12。副模标本是左肱骨的远端部份，编号PIN 4499-14；最后的副模标本是左喙突的肩膀端，编号PIN 4499-13。所有三个化石都存放在俄罗斯科学研究院（The Paleontological Institute of the Russian Academy of Sciences）。肱骨的头阔约29毫米，而白垩纪早期最大型的反鸟亚纲是鹏鸟，其肱骨的头也只有17毫米阔。故此格日勒鸟可能是整个白垩纪中最大型的反鸟亚纲成员。
