Wikipedia references a hadith from page 874 of Encyclopedia of Religion and Nature by Bron Taylor (Google Books) which writes:
He opposed recreational hunting, saying that "whoever shoots at a living creature for sport is cursed."
However, this book has no reference. Googling whoever shoots at a living creature for sport is cursed doesn't help further than this.
Question: Is there a hadith "whoever shoots at a living creature for sport is cursed" and is it authentic?
Yes, there is an authentic hadith to that effect in Sahih Muslim in the book of hunting, slaughter, and what may be eaten:
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا أَبُو بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ مَرَّ ابْنُ عُمَرَ بِفِتْيَانٍ مِنْ قُرَيْشٍ قَدْ نَصَبُوا طَيْرًا وَهُمْ يَرْمُونَهُ وَقَدْ جَعَلُوا لِصَاحِبِ الطَّيْرِ كُلَّ خَاطِئَةٍ مِنْ نَبْلِهِمْ فَلَمَّا رَأَوُا ابْنَ عُمَرَ تَفَرَّقُوا فَقَالَ ابْنُ عُمَرَ مَنْ فَعَلَ هَذَا لَعَنَ اللَّهُ مَنْ فَعَلَ هَذَا إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم لَعَنَ مَنِ اتَّخَذَ شَيْئًا فِيهِ الرُّوحُ غَرَضًا
Sa'id b. Jubair reported that Ibn 'Umar happened to pass by some young men of the Quraish who had tied a bird (and th, is made it a target) at which they had been shooting arrows Every arrow that they missed came into the possession of the owner of the bird. So no sooner did they see Ibn 'Umar they went away. Thereupon Ibn 'Umar said: Who has done this? Allah has cursed him who does this. Verily Allah's Messenger (ﷺ) invoked curse upon one who made a live thing the target (of one's marksmanship).
