We have two new species and a second record for a European species. Some species of warblers appeared to be somewhat more numerous than in previous years. Red-throated Loon : A pair at its now usual haunts on the north-eastern corner of the Isthmus on May 22 is the only report. Common Loon : A few here and there in March for a maximum in St. Pierre of 14 birds on March 31 (PA). The highest concentration was 15 off the west coast of Miquelon on April 12 and 40, same area, on April 21 (RE). A few to the end of the period. Red-necked Grebe : A very low year ! One in St. Pierre harbour from March 7 to 9 (PA). Two only, off Cape Miquelon, on April 22 (RE). Manx Shearwater : About 10 near Colombier island on may 11 (TV). 7 off the south coast of Langlade on May 13 (FPA). A few near Grand Colombier on May 18 (LJ) and about 15 between St. Pierre and Miquelon on May 27 (RE). Northern Gannet : One off the south-west coast of Miquelon on April 5 (LJ) was 17 days earlier than average. The next one was seen only on May 10 south of St. Pierre (TV). A few here and there since, for a maximum of about 20 off the south coast of Langlade on May 13 and a few dozens south of St. Pierre on May 18 (BL). Double-crested Cormorant : The fi rst migrants (2 birds) were seen near the village of Miquelon on April 24, 9 days earlier than average, regularly then and in increasing number (RE). There was a maximum of 8 birds in St. Pierre on April 28 (PA) and 27 on May 18 (PB). American Bittern : One was fl ushed by Denis Detcheverry near Mirande lake on April 28. Great blue Heron : All seen in St. Pierre : Two between April 11 and 14, and one only up to May 5 (m. ob.).
