It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) saw a small bird (hummarah) flying over the heads of his Companions and said: "Who has distressed this one (by taking its young)?" A man from the Ansar said: "I took its eggs, or its chicks." He (peace and blessings be upon him) ordered him to put them back.
