FOR THE BIRDS

JUNE  2002

Sightings

Along Route 22

The last week and a half of May there were 6 Ring-necked Ducks in the pond at Albert Bridge on the right side of Route 22 as you head to Sydney. There were a pair of Red-winged Blackbirds there and at least a dozen Cormorants on the utility lines at the bridge. 

Around the Town

May 21 there were three Tree Swallows flying through the yard of Gladys and Joe Fiander.

Around the Harbour

The Barn Swallows were back at the Fortress site on May 30. June 6 there were about 8 of them hawking for flies along the waterfront of the Fortress site. Bill O’Shea watched two Cliff Swallows about the Administration Compound (park service road) on May 22 and there are now about 8. A Great Blue Heron was flying parallel with our car as we were on the outskirts of Louisbourg the evening of June 6. It landed near Havenside Barachois.

At my Feeders

White-crowned Sparrows are still in the yard. A female Red-winged Blackbird has come in to dine as well as a Northern Flicker that prefers the top of a utility pole as a look-out. He then lands in the yard to hunt for insects. The biggest discovery was the bird I missed. Bill watched a thrush that moved too quickly to identify. It was either a Swainson’s or Grey-cheeked Thrush seen on May 26.

North American Migratory Bird Count

May 11 was foggy early in the morning but the fog was gone by 8:15 a.m. We were lucky enough to see the following birds: 26 Juncos, 8 White-throated Sparrows, 3 Mourning Doves, 4 Crows, 3 Black-capped Chickadees, 8 Purple Finch, a Black and White Warbler, 8 American Goldfinch, a Yellow-rumped Warbler, 6 Pine Siskins, a Yellow-shafted Flicker, Sharp-shinned Hawk, 2 Starlings, 2 Blue Jays, a pair of Brown-headed Cowbirds, a Savannah Sparrow, a Song Sparrow, 4 Common Grackles, a female Rose-breasted Grosbeak, a Chipping Sparrow, a Ruby-throated Hummingbird, 2 Boreal Chickadees and a Baltimore Oriole eating pieces of pear. The pear was left out for the Northern Mockingbird that never made an appearance that day or since, though it was here all winter. Pearl Magee had a Chipping Sparrow, 9 White-throated Sparrows, 2 Savannah Sparrows, a Tree Sparrow, a Song Sparrow and 4 Tree Swallows. She also alerted me to the Ruby-throated Hummingbird so I could rush my feeder out. Carter Stevens had 3 Tree Swallows.

Cowbirds – the birds that take advantage

The male Cowbird is black with a brown head and the female is all gray-brown. What sets Cowbirds aside from other birds we see locally is that the female Cowbird lays her eggs in the nests of other birds. The most commonly used species are Warblers, Vireos, Flycatchers, and Finches. Once a Cowbird lays an egg in another bird’s nest, it’s parental duties are done since the other bird incubates the egg and raises the young. Usually the Cowbird egg hatches slightly ahead of those of the host, giving it a head start on feeding and growing. Female Cowbirds lay an average of 40 eggs per year, but only two to three survive to adulthood. (Stokes Nature Guides—A Guide to Bird Behaviour, Volume II, pp. 213-223)

HAVE A GREAT SUMMER AND KEEP YOUR BINOCULARS NEARBY.
