The Pectoral Sandpiper (Erolia melanotos), Baird's Sandpiper (Erolia bairdii) and Sanderling (Crocethia alba) migrate west of Hudson's Bay in spring (Godfrey, 1966). Of this trio, only one Pectoral Sandpiper was identified, May 15. Cuckoos were not recorded. They were also scarce in the immediate vicinity of Kingston during the migration period but since the series of Breeding Bird Surveys carried out in June showed normal numbers, it is possible that the late spring delayed their arrival to such a degree that they arrived in their breeding localities without stopping off en route. In past years they have been seen in spring and autumn at Passerines. The density of the grounded passerine migrants along Long Point was found to be much higher than has been observed in areas near Kingston. There is evidence that funnelling takes place causing the piling up. Further discussion on this point is to be found in the section Flight Directions below. The numbers of grounded passerines as a result of the weather is given in Table 4. Their number was significantly higher on days associated with stormy weather or frontal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ottawa Field-Naturalists' Club.
