May 12th – International Migratory Bird Day

This is an ideal time to celebrate migrating birds – we’re at the height of their migration. It’s exciting! But before we talk about today we should go over yesterday’s results…..from 3 locations: Ruthven, Fern Hill Oakville, and Lowville Park.

May 11th; Ruthven Park:
An overcast, cooler day with winds from the north. This morning, there was a steady flow of orioles feeding on the Grape Jelly in the martini glass feeder that hangs next to the banding lab . With the oranges that Carol brought, the orioles were well fed and there was even one Orchard Oriole feeding on the jelly, too. The first few net rounds were productive but the numbers dwindled through the morning. Temperatures remained cool and never got above double digits.

We handled twelve Baltimore Orioles and twenty-one American Goldfinches with some older retraps. The bird of the day was an older female Yellow Warbler retrap. She was originally banded on May 13, 2014 as an adult.

May 11th; Fern Hill Oakville:
We opened the nets in a cool easterly wind; and it stayed cool throughout the day. The conditions brought birds to the feeders accounting for the large number of Icterids that we banded (as well as a number of White-crowned Sparrows). A number of the older students were away on school trips so some of the younger, up-and-coming banders got a good opportunity to develop skills.

May 11th; Lowville Park:
This morning started off cold! It was only 2 degrees! I figured this meant for a slow day, but a quick check of NEXRAD radar showed these birds were not going to be stopped by some cold weather and NW winds. The first round was large, with 24 birds captured! The next two rounds were steady but nothing compared to the first. In exciting news the Cerulean Warbler was still singing. First of year birds were Yellow throated vireo, Warbling vireo, Red eyed vireo, Least flycatcher and White crowned sparrow.

May 12th; International Migratory Bird Day:
Not a very auspicious start to the day: cold, NE wind and rain. The rain tailed off around 6:30 and we quickly opened the nets and a couple of traps. Migratory birds were VERY noticeable. Orioles were hitting the grape jelly feeder with gusto; grosbeaks were after the sunflower seeds; and goldfinches were swarming the nijer feeders. We were kept very busy and ended up with our biggest day of the year so far. We banded 91 and handled another 42 retraps (for a total of 133 birds)!

Kind of astonishing: this Yellow Warbler and American Goldfinch were both banded on May 13th, 2017 (ten minutes apart) and then recaptured today (30 minutes apart)! I wonder where they were in-between these encounters. -KMP


Banded 91:
1 Blue-gray Gnatcatcher
4 Gray Catbirds
2 Warbling Vireos
3 Tennessee Warblers
2 Nashville Warblers
21 Yellow Warblers

May 10th – Getting To The Heart Of It

An oldster! This Baltimore Oriole was originally banded May 10th, 2012. At that time it was at least 2 years old, so it’s in at least its 8th year now. Note that it was retrapped once in 2013 and then not again until 2017…and then today. -KAP


One third through May and into the heart of the Spring migration. It’s such an exciting time! You just don’t know what you might find in the forest or…..nets. Some are just passing through – the majority of warbler species – but some are returning to their “summer home”. We are retrapping a good number of long-distance migrants that we banded several years ago. One notable returnee was a male Baltimore Oriole. It was originally banded on May 10th, 2012. At that time it was “aged” as an after second year bird meaning that it had hatched in 2010 or even earlier. It was recaptured once in 2013 and then not seen for a couple of years, not until 2017. And then again this year. Wouldn’t you like to know where it spends the Winter? And how it gets there and back?

Not for the faint of heart! When we were looking a Wood Thrush over for ticks, Karen noticed a lump in the eye. When we removed it we found it to be a leech! I’ve never seen this before. The Thrush was none the worse for the intervention. -KAP


We have been checking migrants out for ticks. When we find any we send them to John Scott at the university of Guelph where he is looking at the possibility that birds might be helping to spread southern tick-borne diseases by transporting the ticks. When Karen was checking out a Wood Thrush this morning she spotted a dark purple orb between the birds eye and the socket. We figured it was a tick but when we removed it found that it was a leech!! I have never seen this before.

Normally a bird of the tree tops, this Great Crested Flycatcher was caught in the lower panel of a net. Maybe looking for shed snakeskin to line its nest with. -KMP

And from Ben Oldfield at Lowville Park on May 9th:
The day started off cool with a lot of activity, looking at NEXRAD radar it was clear migrants were pouring through Ontario last night! In total I banded 25, from 0600-0800. The highlight unfortunately did not fly into the net, but a singing Cerulean Warbler ( a Species at risk) graced the banding area with its song. New arrivals were Magnolia warbler, Ovenbird, Cerulean warbler, Bobolink and Veery.

May 9th – Some Nice Surprises!

Seven years ago – to the day! – Joanne Fleet started volunteering at Ruthven Park. To celebrate the birds conspired to congratulate her and talked this Summer Tanager into making an appearance so she could band it. It’s the first one we’ve ever seen here. There can be no other explanation.


What a delightful day! A school class cancelled (did you know that we have ticks here!?) and some fun bird-people showed up and…we caught some neat birds including the first Summer Tanager at Ruthven!!! We also got two Eastern Kingbirds, a common enough bird but one that we don’t catch very often (just 21 in the past 23 years). Further, there were a lot of birds around. The Birding Machine (Janice Chard and Katherine Paveley) identified 63 species during the hour and a half census, including the first Magnolia Warbler, Blackburnian Warbler, Black-throated Blue Warbler, and Lincoln’s Sparrow of the year.

After a record-setting 63 species seen on census, the team of Janice Chard (left) and Katherine Paveley celebrate. -JDF


Polina (seen with Sain and the pair of Rose-breasted Grosbeaks they banded today) will be heading out tonight for England to pursue bird research. -SEF


On a sad note though, long-time volunteer, McMaster student Polina Utkina, spent her last morning here. She just finished her undergrad degree and is now moving on to pursue birds in Great Britain and beyond. We wish her the best of luck! She couldn’t have left on a better note.

May 7th & 8th – A Hectic Couple Of Days

Male Bay-breasted Warbler. -D. Maida


It’s been a hectic couple of days with school groups and visitors. But the most noticeable thing has been the marked influx of migrants into the area (although not necessarily into the nets). On the 7th we encountered 76 species (including a first ever Summer Tanager, found by Mike Furber along the Fox Den Trail) and today we had 81 Species including 13 types of warbler!

Although it’s been hectic for us, this Racoon doesn’t seem to be fazed by the developments. -D. Maida


American Goldfinches continue to pour through. In these 2 days, between new bandings and retraps we’ve handled 81! Some of the retraps have been 4 or more years old and seem to make Ruthven a regular stopover in both the Spring and Fall (we don’t seem to catch them in the Summer months or in the Winter). They are a great “teaching bird”: easy to extract and handle as well as age and sex and a novice can handle a LOT of them.
