Round one of seven visits to all three MAPS was wrapped up on Saturday, June 6 with our first visit to the Rock Ridge MAPS site in Frontenac Provincial Park. Ontario Parks, particularly the staff at Frontenac, have been of great assistance to FBS getting established. Frontenac Provincial Park, a backcountry wilderness park with over 5000 hectares of incredibly diverse habitats is literally at the core of the Frontenac Breeding Birds program. In addition to the operation of Rock Ridge, we have also started conducting point counts and nest monitoring throughout the park, which will provide a rigorous baseline assessment of breeding bird abundance, species richness, distribution and habitat relationships. A big thanks are due to the following Ontario Parks staff for permitting us to run our project and for assisting in the development of the FBS initiative-Peter Dawson (park superintendant), Bert Korporral, Corina Brdar and Chris Robinson.

Our Rock Ridge Monitoring Avian Productivity and Survivorship (MAPS) site feels, in many ways, like a world apart. The site is as unique as it is beautiful with extensive rock barrens and outcrops that tumble down over steep cliffs into deep clear lakes that shimmer aqua-green in the sun. The steep and rugged cliffs are home to Yellow-rumped Warblers, Pine Warblers, Purple Finches, Northern Rough-winged Swallows and Turkey Vultures to name a few. Frontenac Provincial Park underwent a series of burns about 80 years ago or so. At least one fire that the military had to be called in to put out was started by settlers in a dispute over rights to berry picking territory (blueberries and cranberries)! The human history of Frontenac Provincial Park, while rich and fascinating,  has also played a key role in shaping what is there today. The burns of the 30’s have resulted in a large swath of what is best described as rock barren habitat with stunted and slow growing plant communities. This is a fascinating habitat and a clear favourite of Field Sparrows, Eastern Towhees and a few specialists of the region (more on that later this week).

The photo above was taken near the banding station during a brief sunny period on our visit. The view takes us over steep cliffs of conifers across to wetlands that include a small Black Spruce bog. The MAPS site also includes some more mature mixed-forest along the northwestern side. The White-throated Sparrow such as the one pictured above are one of the most abundant species at the station and their distinctive voices filled the air from all directions during our visit.

Access to Rock Ridge is at best an ordeal of mental and physical stamina! Waking up at 3am never gets easy and then to undertake a 30 minute drive followed by a 30 minute portage and 20 minute paddle….you get the picture. However, Rock Ridge is worth it. This is the view from the banding station where all of the captured birds during the six hours of mistnetting are processed (banded, measured, aged, sexed and released). There is just something of the untouched about the place that makes it all worthwhile and the birds are terrific as well. Actually, I had an hour or two of panic when we had caught a promising four birds on the first net check, which was followed by three consecutive rounds of absolutely nothing. Fortunately, a total of fifteen birds were captured during the following three net checks!

Speaking of birds, we ended the day having banded a total of 23 birds and 2 repeat captures for a total of 25. The most common of the lot were American Robins (4) followed by Red-eyed Vireo (3) and White-throated Sparrow (3). Nashville Warbler, Yellow-rumped Warbler, Scarlet Tanager and Purple Finch are also quite numerous at the site but all evaded our nets on the first day. There were also a few “singles of things” such as this second-calender year female Eastern Kingbird.

Black-and-white Warbler (Leckie)
Black-and-white Warbler (Leckie)

Black-and-white Warblers occur in significant numbers at all three MAPS stations. We managed to catch this sharp male from one of our “scrub” nets that is far from appropriate habitat for this species. They tend to be most common along the more maturely wooded slopes but they do seem to occur in some rather open and stunted habitats as well.

Black-billed Cuckoo (Leckie)
Black-billed Cuckoo (Leckie)

Cuckoos, both Black-billed and Yellow-billed are also found at all three MAPS sites. We captured this Black-billed and narrowly missed another in net 10 around late morning (they are a bit on the large side for 30mm mesh nets and tend to flop out when approached). The incredible abundance of forest tent caterpillars this year may produce a bumper crop of juv cuckoos in 2009!

Cedar Waxwing (Leckie)
Cedar Waxwing (Leckie)

Cedar Waxwings are late nesters and tend not to get down to business until late June-early July in Ontario. Wheeling flocks of Cedar Waxwings have been observed on a regular basis at our MAPS sites but this is the first of the species that we’ve caught. Seabrooke must have enjoyed the light of Rock Ridge as these bird portraits are particularly strong. Seabrooke has been a huge help to the operation of these MAPS stations as I’m doubtful that this could have been pulled off on my own. Look for her account of Rock Ridge on her marvelous blog later today!

Red-eyed Vireo (Derbyshire)

In the end, our first visit to Rock Ridge was a productive one as we experienced no major incidents in accessing the site and the sample of breeding birds was very strong. I have a feeling that, more so than the other sites, the composition of species in our sample will change most sharply for Rock Ridge as the canopy birds descend and the site funnels a high number of late summer dispersing adults and young. That’s just my hunch…..

Scouting for M.A.P.S-Maplewood Bog

Maplewood Bog MAPS Station

This is our preview of the Maplewood Bog MAPS site, one of three stations in our soon to be realized MAPS network in the FBS study area. The Hemlock Lake MAPS station was previewed here last week. Maplewood Bog (MABO) is another very interesting site and has more of a deciduous “flavour” than the other two stations in the area. The site was named after the abundance of maple here and the presence of several rich bog environments. A visit to the site yesterday afternoon revealed a diverse abundance of breeding birds, which included Black-and-white Warblers, Scarlet Tanagers, American Redstarts, Ovenbirds, White-throated Sparrows, Blue-headed Vireo, Veery and a “good” number of Wood Thrushes.

Much like the Hemlock Lake site, the 20 hectare Maplewood Bog station is highly varied with dry oak-juniper savannah, mature decidous forest & patchy mixed forest as well as many streams, bogs and a large lake to the west. Eastern Towhee and Field Sparrows were common in the dryer open habitats, while Scarlet Tanagers and a Yellow-throated Vireo sang from the mature woodland less than 50m away.

Edges can be hard to find in this heavily wooded area of the Frontenac Arch. These edges are important features for sampling dispersing young birds in mid-late summer. Adult birds can be readily captured and banded in forest interior locations during the early part of the summer but these locations are often vacated once young have fledged. Therefore, in establishing a new MAPS site, we try to arrive at a balanced selection of interior and edge locations for mistnets, which should maximize sample for the extent of the breeding season. In this region, wetlands and clearings provide the important balance to forest-interior netting sites.

For me the most compelling aspect of this site is the abundance of deciduous forest species, particularly the thrushes. I encountered several Veery and at least three Wood Thrushes that seemed to be holding territories. With many more birds yet to arrive, this site should have a great mix of species and will be a very nice compliment to the more coniferous obligate species of Hemlock Lake. I managed to record this singing Wood Thrush with my new microphone and have uploaded a short piece of it below (click play button).

Scouting for M.A.P.S- Hemlock Lake

Hemlock Lake MAPS Site
Hemlock Lake MAPS Site

All of the needed permits and agreements are now in place to move forward with more detailed planning for the installation of three Monitoring Avian Productivity and Survivorship (MAPS) stations in our study area. With the study area being over 15,000 hectares in size, it has been a big project just to develop a basic framework for maximizing the utility of the MAPS program for the purposes of our Frontenac Breeding Birds initiative. From the beginning it was clear that one station would be good, two would be better and that three could be a powerfully instructive network of stations that could calculate and monitor avian demographics for an area of approximately 22,000 hectares (not bad for 21 days of fieldwork!). This initiative also represents the first major expansion of the MAPS program in Ontario since 1995 when a total of six stations were simultaneously initiated in 1995 at Kakabeka Falls in Northwestern Ontario, all of which closed in 1998 (there have been a few isolated stations added in the province since that time). It is our intention to continue adding stations in strategic areas as we move forward. However, establishing these first three will be important to understand appropriate criteria for future expansion and to test feasibility of specific landscape components for the MAPS program in this region.

Young hardwood forest swamp

Selecting suitable sites for MAPS is a slightly tricky business as many factors have to be considered including access, habitat components, species assemblage as well as proximity of infrastructure, development and agricultural activity. In developing our MAPS network we were careful to consider sites that could be accessed relatively comfortably and that were fairly consistent in degree and type of anthropogenic pressure, habitat maturity and habitat structure. However, a hallmark of the Frontenac Axis is its heterogeneity, and it is true that something quite different can be found at any turn. All three of our sites are similar but will have distinct characteristics of slope, vegetation, hydrology and representative bird species. This will allow us to sample a broad array of breeding bird species and also provide the opportunity to study some species shared by all three stations that are occurring in differing landscape contexts.

The panoramic image above was taken from our new Hemlock Lake (codename HELA) site, which is a site that I’ve been very keen on since my first visit in January, 2009. The site is a spectacular example of the Frontenac Axis with shield-like features and characteristically southern forest elements. The 20ha site is focused around a small lake with hundreds of flooded snags. The perimeter of this lake is very rocky with meandering creeks and small wetlands. The habitat is predominantly successional coniferous forest with young hardwood communities, however mature mixed-forest and juniper-rock barrens are also abundant in the area. A visit to the site yesterday was very buggy to say the least but I did find an impressive community of birds, which seemed to be on territory within the site. A shortlist of the species mix is provided below. We will return to this site once the Black Flies have relented to set up for our first banding day in early June, 2009. It is going to be an absolute pleasure to spend seven summer mornings with the birds at Hemlock Lake!

2009 MAPS Habitat?

I spent the better part of yesterday afternoon scouting possible sites for our intended MAPS stations in the FBS study area. Frontenac Breeding Birds is the flagship program of Frontenac Bird Studies set for launch in mid-May, 2009. This program is being developed for the purpose of long-term inventory, monitoring and research of the region’s breeding bird populations. The Ontario Breeding Bird Atlas (OBBA) and North American Breeding Bird Survey (BBS) are two excellent sources of data that reveal long-term changes in population size and distribution of breeding birds. Across the continent, state/provincial atlas programs and BBS survey routes are extensive in coverage, providing an important foundation for monitoring bird populations. You may be thinking “why bother establishing Frontenac Breeding Birds?”

Both the OBBA and the BBS programs are devoted to monitoring bird populations at a broad scale, such as a province, state, country and/or continent. These programs are therefore “extensive” in their focus rather than “intensive”. Used in conjunction, these programs are a critical barometer of population trends that pinpoint regions or species of particular concern for conservation. The recently published 2nd edition of the Ontario Breeding Bird Atlas clearly indicated a marked association of the Frontenac Arch ecotone as a sort of “stronghold” for many of Ontario’s bird species, including a high number of Species at Risk. The goal of our Frontenac Breeding Birds program is to take this important direction and further the understanding and awareness of bird populations in the Frontenac region by way of increased effort, an integrated approach to monitoring and by initiating more specific studies. Observational survey methods used by the OBBA and BBS were designed to index population size and range for North American bird species. Having this knowledge is a critical first step in the process of establishing priorities for conservation and research. The Frontenac Breeding Birds program represents an intensified and more comprehensive monitoring regime for breeding birds in the Frontenac Arch, a region of high conservation concern. Our approach will include annual monitoring of breeding bird demographics through the installation of a network of Monitoring Avian Productivity and Survivorship (MAPS) stations.

Modeled after the Constant Effort Ringing scheme in the United Kingdom, the Monitoring Avian Productivity and Survivorship (MAPS) program was initiated in 1989 to provide long-term demographic data for North American landbirds. After a four-year pilot study, the MAPS program was endorsed by Partners in Flight, U.S. Geological Survey and the U.S. Fish and Wildlife Service indicating that MAPS was “the most important project in the nongame bird monitoring arena since the creation of the Breeding Bird Survey”. Over 1000 MAPS stations have been activated in the United States since 1989 contributing heavily to research, land management and conservation strategies. So far, Ontario has lagged behind in having less than 10 active MAPS stations in total. A MAPS network in the FBS study area will procure the first-ever index of demographics for local breeding bird populations and with subsequent annual monitoring, will serve as a barometer of the health and vitality of associated habitats. At the local and regional level, the incorporation of a MAPS network is a cost-efficient strategy for evaluating ecological stability in the landscape as a single station alone can yield vital rate statistics for an area up to 12,000 hectares from the centre of each station (due to post-fledging dispersal). This MAPS network would provide a valuable tool to evaluate management actions and various magnitudes and types of environmental and anthropogenic influence. We are also hoping to promote the MAPS program across southern and central Ontario where increased effort and participation could be of considerable ornithological and conservation value.

The majority of the FBS study area is privately-owned, which presents a challenge to find sites of a suitable nature and where permission to do the work can be obtained. Fortunately, the region has a good selection of protected land owned by the crown and municipal government. We are still in the process of selecting sites for MAPS but we are intending to install two or more stations in 2009 that will sample representative species and habitats of the region. The following is a sneak preview of some of these potential sites.

Frontenac Provincial Park (near Dipper Bay, Birch Lake)

Mature deciduous forest interspersed with lakes, beaver ponds and ephemeral creeks is a dominant habitat type in the area. Valleys often contain a denser shrub layer, vernal pools and flooded forest. Ridges typically have characteristic upland oak-juniper savannah. Charactertistic tree species include Oak, Maple, Ash, Birch, Beech and lesser quantities of Ironwood, Basswood and Shagbark hickory to name a few. Barred Owl, Red-shouldered Hawk and Cerulean Warbler are common to these forests.

Large Beaver Pond in hemlock forest type

This is an example of a large pond created by beavers in another tract to the north of Frontenac Provincial Park. This habitat is mixed-coniferous with cedar and hemlock being dominant tree species. These areas are characteristically wet with a dense understory of coniferous saplings and herbaceous plants. Wetlands occur throughout and include some bog environments. Typical bird species of this forest type should be Winter Wren, White-throated Sparrow, Magnolia Warbler and Hermit Thrush to name a few. The picture above is classic of the Frontenac Arch where the landscape transitions to Canadian Shield.

Dan's eye-view of the forest interior

Here is a closer view of this habitat type. This will certainly be the most difficult terrain to navigate due to the dense growth and preponderance of wet and mossy dead snags and stumps. However, we will happily sacrifice our shins for the opportunity to learn more about this fascinating habitat and its inhabitants!

Bog environment near Devil Lake Road

I visited this bog habitat in another tract to the east. This wetland already contains Swamp Sparrow and Wood Ducks and various woodpecker species (and a varied cast of vocal amphibians!). The number of wetlands of various kinds in the area is quite remarkable, which provides an interesting and ever changing blend of aquatic and terrestrial birds on any given hike. There are also acidic tamarack-spruce bogs in the area, which consist of carniverous plants and other truly northern specialties (more on these spruce bogs later).

The MAPS stations will begin operating in late May-early June, which gives us some time to finalize our site plans, order equipment and look forward to many early mornings with birds in summer 2009! Stay tuned for more details……
