For members of OFO, you have.... or will be receiving in the next day or two.... the April issue of Ontario Birds; it has 56 pages comprised of five articles. The cover painting of Barn Swallows at a nest by Barry Kent MacKay is an artistic nod-into an article by Al Sandilands and Derek Morningstar on a new DNA technique (next generation sampling) to identify diet items in avian insectivore nestlings. The lead article is a very timely account on the 2017 influx of Dickcissels into Ontario by Allen Woodliffe. This is followed by a rarely observed instance of a female Brown-headed Cowbird exploring the nest entrance of a Black-capped Chickadee at Rondeau Provincial Park by Warren Dunlop and five others. Harry Lumsden and two co-authors next present an account of territorial displays (one of which was previously unknown) by Mute Swans. The final article in this issue is a description of the interspecific pairing of a Tree Swallow and a Violet-green Swallow in Thunder Bay by Ted Armstrong and Christine Johnson. We are happy to announce that we have almost a full slate of articles for the August issue (deadline 1 July) and are taking submissions for our December issue (deadline 15 October).
