Peregrine Falcon: A New Breeding Species for the Island of Newfoundland

Peregrine Falcon was once an endangered species across North America. In the mid 1960's to 70's they were on the brink of extinction in our continent, largely due to the use of DDT - an insecticide. Thanks to the work of Rachel Carson, her book Silent Spring, and the efforts of many others, DDT was banned from use in 1972. Since then, with the help of recovery efforts, Peregrine Falcons have made a remarkable comeback across the entire continent. They now breed in all states, provinces, and territories (expect, maybe, PEI?)

Despite being a regular breeder in the mountains of Labrador, there was never a confirmed breeding record for the island of Newfoundland, until now.

Laura King first reported a pair near a seabird colony in early May, 2018. A couple weeks later Brendan Kelly found them at the same location and noted their "nesty" behaviour. In mid August, while out on a hike with Mike (a childhood friend), we came across a single adult feeding 2 begging juveniles. A long-overdue first breeding record for the island, but nonetheless exciting. The site will be monitored in the coming years, and hopefully there'll be more Peregrine nests discovered in the not to distant future. There certainly is no lack of cliffs and food in the way of seabirds for these birds to spread across the island.

Note that this adult has already begun its pre-basic molt. Falcons are unusual in that their wing molt begins with p4 and s5 (the midpoint of the primaries and secondaries) rather than the more conventional innermost primary as with most other bird species. No one knows why this is.





The adult delivers a juvenile Common Tern to its freshly fledged youngster.

July Weekend Warrior

This blog is low on the list of priorities these days and probably forever...

Weekends are my main opportunity to get out and explore. Here are some recent photos:

This Little Egret was only the 11th record for the province. It has been reliably seen at Spaniard's Bay for over 4 weeks now.

An unusually early Lesser Scaup was back at the local moulting pond. In previous years they returned in late August or September.

For the 5th year running we've had a Tufted Duck spend the entire summer season in St. John's.
The Iceland migrants start coming back in the first few days of August.

Another unusual mid-summer bird was this American Coot. We still don't have a confirmed breeding record for the island of Newfoundland:

This flock of kittiwakes at Trepassey this morning included one smaller gull with a sooty mantle.

Based on its relatively small size I was sure it was a Franklin's Gull 

It eventually did one fly-by revealing its true identity as the more expected, but still rare, Laughing Gull.

It is in first summer plumage. Distinguished from Franklin's Gull by the complete dark tail-band, and slightly drooping bill.


Nearby a small forest fire was giving the water bomber some early summer practice:






The true aerial experts were showing off at Ferryland:

Arctic Terns are an uncommon breeding species around the Avalon. There must be a decent sized colony on one of the offshore islands at Ferryland as they almost always seem to be doing rounds of the main beach:


Today they were taking advantage of the rolling capelin:

The Twillicks - 2018 Birdathon

For the fourth year running, Catherine Barrett and I took part in the annual Great Canadian Birdathon.

We started on Saturday evening (9 June) in the greater St. John's area, before heading 'down' the Southern shore on Sunday at 4am. We finished at 6pm on Sunday.

Our species list is below including the first location each species was recorded.

We broke our previous record of 96 species, recording .... 97 species! A new record big day for the Avalon peninsula.

2015: 92
2016: 95
2017: 90
2018: 97

Some obvious misses this year include:
Greater Scaup, Willow Ptarmigan, Great Cormorant, Willet, Downy Woodpecker,  Northern Saw-whet Owl, Great Horned Owl, Alder Flycatcher, and Mourning Warbler.

With more time to scout out some of those species we could have easily seen 100 and then some. It'll have to wait for another year!

We've raised ~$1300 for Bird Studies Canada and Nature NL. If you'd like to contribute, here is the link to donate:
