July 9th – Demanding Adults…Demanding Children

An adult male Baltimore Oriole is joined at the jam feeder by a young one – which is making quite a racket with its begging calls with wing quivering for emphasis. -DOL


The whining pays off as the male stuffs some jam into the young one’s mouth. -DOL


Since early May, when the returning migrant orioles found our two jam feeders, there has been constant traffic from the trees to the jam, back to the trees. Initially it was pretty frenetic and I think we were attracting birds from quite a wide area. [I watched one bird fly from the other side of the Grand River directly to our feeder and then back again, a distance I would estimate of at least 300 meters.] Once territorial disputes were sorted out and nest-building commenced, the flow slowed down – but never stopped. We knew females were sitting on eggs when their presence was just occasional even though the males came often.

Note the jam on this bird’s bill. They have “brushes” on the end of their tongues which make gobbling up jam (or flower nectar) quite easy. -DOL


Throughout this time the adults were very definite in what they thought we should be providing. We would take the martini glasses in at night to clean them and then refill them in readiness for the next day. But if they weren’t out there by the crack of dawn we heard about!

It’s been interesting to watch the young ones learn how to “navigate” the jam feeder. Initially some have done face plants into the sugary confection and others have stumbled into it and have to wade across (later picking the jam off their feet and legs). -DOL


Then, around the beginning of July, another chord (or I guess I should say dischord) was added: the incessant begging chatter of the juveniles:”FEED ME”!!! The adults tend the young for about 12-14 days after fledging. The young birds have a lot to learn: how to fly and navigate through trees and shrubs; how to feed and what to feed on; what to be vigilant about. It’s been interesting to watch the juveniles around the jam feeders. The adults get them as far as perching on the basket rim and will feed them in that position but the young ones have to learn how to navigate the wire on their own. I have seen this result in “face plants” into the jam or a tumble into it resulting in their having to wade to the other side (and then slurp the jam off their legs/feet). But they’re learning quickly and mistakes are happening less and less frequently. Soon the adults will cut them loose – the juveniles will be completely on their own while their parents find a safe place to go through a complete moult, replacing all their feathers before they head south.

We’ve seen as many as 5 birds trying to access the same feeder. -DOL

When that happens the young birds will remain in the general area but will begin to expand their radius (“disperse”) as they scope out the various local habitats with a view to where they might like to set up a territory next Spring. In the meantime they will have to watch out for predators. I have yet to see an accipiter in the yard but I’m sure it’s just a matter of time before the “noise” attracts one.

June 21st – A New Project

Recently-fledged Tree Swallows are starting to line the wires. Fall migration can’t be too far away. -DOL


To help pass this stay-at-home period and too organize my time, I’ve been trying to come up with a project I can do daily that a) is interesting (to me); b) doesn’t involve the skilled use of tools (to which I’m allergic); c) might provide useful data over time; and d) won’t eat up too much time.

I’ve been trying to keep active every day, usually by doing some cycling, much of it along reclaimed railroad beds in the area. There’s a really good 18.5 km loop that runs from York, NE along Regional Road 9 to the Gypsum Mine Tract Trail, along it to McClung Road in Caledonia, south down McClung to the Grand River, and then back to York along the Rotary Club Riverside Trail. And to get into Hamilton, I follow the first part of this loop to McClung Rd and then take the Chippawa Trail to Albion Falls and the Mountain brow. [The other day I hopped onto the Chippawa Trail where it crosses Unity Rd. right next to the Kilman Zoo. One of the lions started roaring. I had never heard this in Africa. It is REALLY impressive. Don’t think I’d want to hear it right outside my tent though.]

The thing I’ve noticed about these trails is that they’re bordered by fairly dense vegetation ranging from shrubs to stands of trees; in fact, in some places the trails go through actual forest. As cities continue to expand these vegetated corridors will become ever more important for wildlife – for both flora and fauna. What do we know about the trails in our area right now? What species of birds nest along them? Do birds move along them during migration? Do animals travel along them from one area to another? I don’t think we know much; I’m not aware of any assessment that’s been done (if there has been some I’d love to know about it!).

So….as often as possible I’m going to take an hour in the morning to walk a section of the Gypsum Mine Tract Trail (the newest one) and do a bird count. I’ll post the results on eBird so there’s a record. Sometime in the future, during migration, I’d love to net along the trail in one spot and run another set of nets a kilometer further along to see if migrants continue to move during the day using these corridors. I did the section between Young’s Rd. and Stoney Creek Rd. this morning and came up with 33 species including Yellow-billed Cuckoo (at least 4 of them).

June 9th – Unfortunate Timing

Eila chanced upon this Least Bittern and (unusual for her) had her camera ready to go. What a nice find!! -ELO


The banding season may be over but the birding season…..well, there simply isn’t a birding season – it’s all the time. A wide variety of people (of all ages) have been sending me anecdotal reports of their sightings and/or photos. Almost invariably they comment that they’re surprised that there’s so many neat birds in their immediate areas – they had no idea. Further, they’re surprised (sometimes amazed) that there are so many wild spaces around them. Some small, some large…but, again, they just weren’t aware that they existed. This is one of the positive spin-offs of COVID-19: people are paying attention to the natural world right around them.

To my mind though it might have been better if this pandemic, which is requiring that people stay home or close to it, started next year – the beginning of the collection of data for the Ontario Breeding Bird Atlas. Just think of all the people searching out birds in their immediate neighbourhoods right at the moment. Let’s hope this zeal hasn’t worn off next year – it could result in a hell of an atlas!

This European Starling has found a good place to look for insects. -ELO


I was intrigued by this shot of a European Starling adapting to its habitat. They’re a pretty clover bird! I remember once watching a very resourceful starling: I was driving on the I 90 – the New York Thruway. There was a big lineup of cars and trucks at a toll booth moving very slowly. This starling would go through the grill of the trucks and emerge with a big insect (presumably toasted) which it would whisk away for its young. Minutes later it would be back, sometimes to another truck. How did it ever manage to learn that this was even an option!?

I’ve included a bunch of photos that folks have sent me at the end. But I thought I’d like to throw in this delightful letter from Kip. He and his folks have visited Ruthven on a few occasions and the little guy apparently is turning into a keen observer and birder…..as you will see.

June 4th – Summing Up The Spring Season

A Common Grackle beats the heat (and cleans up) in a puddle. -MMG


The dust is settling on the 25th consecutive Spring migration monitoring season at Ruthven. Needless to say, it was very different. Access to the park was severely restricted to just a few people on any one day – usually just two: the bander-in-charge, and a person to do census. Later, in May, when restrictions began to loosen, I would have a person in to help with net rounds or to continue their studies/experiences in banding under my tutelage, trying to maintain physical distancing as much as possible and disinfecting tools after each session. This seems to have worked well – we got the job done and NO ONE GOT SICK – but the camaraderie that has been the hallmark of the operation for the past many years was missing. I think I missed this most of all. Still, we were there to monitor the migration, not have fun….right?

The month of April was a disaster: due to prolonged bouts of cold, wet, windy weather our banding total was only 489 birds, one of the lowest totals in our history and more than 200 birds below the 10-year average of 693 birds. The birds caught per 100 net hours (1 net hour = one 12-meter net open for one hour) was the lowest going back to 2010 – 14.94. Birds generally were few and far between and migrants were quite late. For example, we can expect to see Purple Martins during the first week of April; this season they didn’t show until the beginning of May. Other migrants were 7-10 days late on average. I keep track of the average number of birds banded per 10 period in both April and May. We were well below average in each “trimester” in April.

May started off slowly, again due to poor weather conditions. The ist trimester, when we band an average 44.1 birds per day, was low – 33 birds per day. But then things picked up substantially and from May 15th – 24th the bulk of migrants blew through. During the second trimester we averaged 55 birds banded per day (vs 44.8) and this push continued through the 3rd period – 28 birds (vs 24.4). Our May total of 1,186 was well above the 10-year average of 1,120.

Due to our success in May, our overall total of 1,675 birds banded is not only respectable but above the 10-year average (1,622). The birds banded per 100 net hours in May (33.98) and for the whole season (26.36) ranked as the 3rd highest in both cases. So….we were able to make somethin’ out of nothin’ so to speak. Also, we banded an amazing 90 species – our 2nd highest total. Noteable bandings included: 1 American Woodcock (not an uncommon bird but rarely seen or captured), 1 Sharp-shinned Hawk, 1 Grasshopper Sparrow (a first for the station), and a female Cerulean Warbler (a species that is in trouble).

The treat of the season: female Cerulean Warbler. -KMP

But migration monitoring is more than just banding birds. An integral part of it is to identify and count the various species that move though/by the site each day. This is where the census is so important as it samples a part of the site that is separate and largely ecologically different from the banding/netting area (e.g., the river, the inner forest). This season we encountered 149 species which included 3 species “new” to Ruthven: Grasshopper Sparrow, American White Pelican, and Lesser Scaup. Warblers made up 25 of those species. We banded significantly higher numbers of a few warbler species: Nashville Warbler (56), Northern Parula (6), Black-throated Green Warbler (4), Western Palm Warbler (39), and Northern Waterthrush (9).

The most notable species banded to my way of thinking was the Baltimore Oriole. We set a record last year of 117; we extended that record this year to 122! Is this due to the jam/jelly feeder or are their numbers simply increasing – it will be difficult to compare results this year as most stations did not operate…..

Thanks to all that pitched in to help out!! I think this formal scheduled access will be the way of doing things for at least the next season – if not even longer. We will have to see how things unfold.

Top Ten:
122 Baltimore Orioles
110 American Goldfinches
108 Brown-headed Cowbirds
102 White-throated Sparrows
74 Gray Catbirds
72 Yellow Warblers
59 Ruby-crowned Kinglets
59 Chipping Sparrows
58 Song Sparrows
56 Nashville Warblers
56 Red-winged Blackbirds
