Hello Ontbirders

Several interesting sightings this morning in areas east of Ottawa.

Petrie Island
At the marsh on the west side of the Trim Road causeway there was:
* 1 Least Bittern
* 2 adult Sora
* 2 adult Black Terns
Directions courtesy Neily World: http://ca.geocities.com/[EMAIL PROTECTED]/oreo9.htm

Dignard Constructed Wetland
In the manure pile, and the two smallest west cells, there were:
* 3 Solitary Sandpipers
* 2 Semipalmated Sandpipers
* 25 Least Sandpipers
* A Horned Lark, and families of Spotted Sandpiper and Killdeer were also present.
Directions: From Hwy 417 go south on Hwy 28 to Route 300.
The wetland is on farm property at the southeast corner of Route 300 and Hwy 28 (Northwest of Embrun). Route 300 turns left only (northeast) of Hwy 28. Look for the large "Dignard Constructed Wetland" sign on your right hand side. The "South Nation Conservation" request that birders park on the side of the road, and respect the farm's private property.

Embrun Sewage Lagoons
In the upper cells there were several ducks including:
* 1 male Redhead
* 2 male and 1 female Ruddy Ducks
* Flying overhead was a Semipalmated Plover.
* In the plowed field on the southeast side of the lagoons were 14 Upland Sandpipers. Directions courtesy Neily World: http://ca.geocities.com/[EMAIL PROTECTED]/sewage4.htm

Cheerio & Good Luck

I birded the lagoons for 1.5 hours this morning before noon. I had many of the species reported yesterday by Dave Wornington with a few changes in numbers. These lagoons remind me of the Port Perry "Nonquon" Sewage Lagoons in their former glory days before they were "improved" for waste water treatment. It's just a matter of time until the Holland Landing Lagoons produce rare shorebirds given the excellent habitat there now. In fact this is the best time to look for mega rarities from the Old World such as adult Little Stint and adult Spotted Redshank and other adult shorebirds which are still mostly in alternate (breeding) plumage now.

Today's birds at Holland Landing Sewage Lagoons included:

Short-billed Dowitcher: One adult. Dave reported a "brightly plumaged" individual yesterday. Today it was still there I presume. It's a good example of the 'hendersoni' subspecies in alternate plumage which breeds west of Hudson Bay to northeastern British Columbia. It is by far the commoner of the two subspecies (griseus and hendersoni) in southern Ontario, particularly for southbound migrants. The two subspecies are best illustrated in the 3rd and 4th editions of the National Geographic Field Guide. These editions of the NGG also best show the differences between Short-billed and Long-billed Dowitchers. Adult Long-billed are very rare here in late July and August into September). First juvenile Short-billed expected during first week of August. First juvenile Long-billed expected about mid-September, but I saw one the last day of August years ago.

81 Least Sandpipers: These included two fresh juveniles which were my first of the year. The percentage of juveniles will increase daily. The reddish juveniles contrast well among the worn darker adults.

Semipalmated Sandpiper: Only one! Adult numbers seem very low so far this year. First juveniles expected about 1 August or a little earlier.

19 Lesser Yellowlegs: all adults in worn alternate plumage showing early stages of prebasic body molt with contrasting new grey basic (winter) feathers scattered above. Expect to see "brand new" spangled juveniles any day now. They stick out among the worn and patchy adults.

10 Solitary Sandpipers: All adults in worn alternate plumage with most the white feather tips worn off. First juveniles expected in a week to 10 days. These juveniles with numerous buffy-white spots above will contrast with the worn adults, which have lost much of their pale spotting above.

Spotted Sandpiper: Many adults (spotted) and juveniles (no spots). Adults do not molt until they reach the wintering grounds so adults and juveniles are easily told apart all summer into early fall. We normally do not see adults here in winter plumage - the unspotted ones are juveniles not winter adults.

Killdeer: Many full grown juveniles still with attached downy tail streamers. Juveniles are also much greyer above whereas adults are a worn reddish brown.

Bonaparte's Gulls: About a dozen birds including one with almost a full hood. They all were year-old nonbreeding birds molting to basic (winter) plumage. These year-old birds begin and complete their molting before the breeding adults and juveniles. Gaps in their flight feathers indicated that they were in wing molt. The first adults from the boreal nesting grounds should arrive soon followed shortly by the first juveniles. These adults and juveniles will molt mainly during August into September. Watch the stages of the molt.

Small flock of about 20 mixed Blue-winged and Green-winged Teal in basic (eclipse/winter) plumage. Numbers of mid-summer Blue-winged Teal are way down from 25 years ago. Why?

Osprey: While there an adult Osprey flew in from the north and dived down out of my sight into a lagoon and came up with a bunch of weeds hanging from its feet (no fish in ponds). It quickly flew off trailing the vegetation and presumed prey which I couldn't see. I figure it caught a Green Frog because they were calling loudly from that lagoon. A week ago I saw an Osprey do exactly the same thing there.

Before you go shorebirding you might want to buy the newest shorebird book titled "The Shorebird Guide" by Michael O'Brien, Richard Grossely and Kevin Karlson, published in 2006 by Houghton Mifflin Company. Great photos of juveniles and adults, molting birds, etc. Excellent text. It's only $33.95 at Open Air Books in Toronto. I'll be reviewing it fully in the August issue of Ontario Birds.

I recommend a tour of the Holland Landing Sewage Lagoons. Directions from Toronto: Go north on DVP - 404 to end at Green Lane. Turn left going several km to Yonge Street. Turn right on Yonge and go about 2 km and exit right to Holland Landing (well signed). You'll be on Old Yonge Street so keep going north several km through town. You will go by a curve in the road where there are pine stands on both sides, then you will pass Doane Rd. on the right. About another km you will see two white wagon wheels and a Max 60 sign at Cedar St. Turn right (east) and follow it 1 km to a dead end. The lagoons are straight ahead.

Get out and look at shorebirds - they're fascinating.
