Purple Gallinule (Porphyrio martinica): Newfoundland Rare Bird of 2018
The rarest bird sighted in 2018 was the purple gallinule on the Waterford River in St. John’s. There have been more than a dozen recorded sightings in the past, typically on a ship or in a random back garden only to be seen briefly and never again. This bird was different. It was present for about six weeks from mid-May and into June.
As 2018 comes to a close it is time to look back at the birding year in Newfoundland. According to my calculations 272 species of birds were observed on the island of Newfoundland in 2018. This grand total is on par with recent years.

Crayfish - Invaders from the Bayou
Of all of the aquatic animals that could be collected in a gillnet on the Kenai River, crawfish are some of the least likely. Why? Because they do not naturally occur in the Kenai River or any other river in Alaska. Unfortunately, crawfish have been collected from the lower Kenai River twice in the last four years, and both times they were leftovers from someone’s dinner.
