Rouge River Bird Observatory |
June 2006:
26 June: We received report of an interesting recovery of one of our banded birds. A White-throated Sparrow that we banded here as an adult on 6 October 1999 was recaptured on 16 April 2006 at Dunblane Hills Research station, at the base of the Bruce Peninsula in Ontario, an operation of the Bruce Peninsula Bird Observatory. This bird is at least seven years old.
14 June: Spring banding results are posted here, and there is a link to a new issue of the RRBO newsletter here.
1 June: An incredibly late Winter Wren was singing in the floodplain today.
May 2006:
28 May: A late Blue-winged Warbler was one of the few migrants present today.
27 May: A few migrants still hanging around, including Swainson's Thrush, Blackburnian, Tennessee, and Wilson's Warblers, and a White-crowned Sparrow.
26 May: No Kentucky Warbler today, but a flyover American Pipit was a very interesting record. There was also a Worm-eating Warbler in the Hickory Meadow in mid-afternoon which was not relocated later. We had another late Ruby-crowned Kinglet and a new late date for Blue-winged Warbler. Flycatchers are becoming more common. Two singing Blackburnian Warblers and a Black-throated Green Warbler are also getting towards the end of their migration window.
25 May: A Kentucky Warbler was found today, singing in the area between the Rose Garden and the Lake. White-throated Sparrow, White-crowned Sparrow, and the first Yellow-bellied Flycatcher of the spring were banded today.
24 May: A late female Northern Parula was seen in east Dearborn today. The first Common Nighthawks were widely reported in the region last night.
21 May: Depressed numbers and diversity more reminiscent of early spring today. A Ruby-crowned Kinglet was a record late date. Two Blue-headed Vireos were also getting late. At least 30 White-crowned Sparrows are still present, at a time when they tend to be nearly all gone. White-throated Sparrows, Black-and-white Warblers, Yellow-rumped Warblers, and Black-throated Green Warblers are all early migrants that are still present.
18 May: Despite last night's rain and the strong north winds that continue today, there were more birds around. Many of the species that appeared in slightly higher numbers today are still early-season migrants, such as Yellow-rumped Warblers, Black-throated Green Warblers, and Black-and-White Warbler. Blackpoll Warblers arrived, and a Yellow-bellied Sapsucker was getting late. A Clay-colored Sparrow was found on the concrete channel of the Rouge River.
17 May: A female Yellow-breasted Chat was banded today. Otherwise it was very quiet.
16 May: A singing male Hooded Warbler was near the Rose Garden gazebo, the traditional Hooded Warbler "hotspot." A Louisiana Waterthrush was along the lakeside trail.
15 May: Canada Warblers arrived today.
12 May: With the rain and wind, not as much activity. Mourning Warbler is a new arrival.
10 May: New arrivals include Scarlet Tanager, Bay-breasted Warbler, Wilson's Warbler, and Yellow-throated Vireo. Six Cape May Warblers is a good number for this species. One of the Blue-winged Teal made an appearance, and there was a report of an Orchard Oriole.
9 May: Green Herons, Eastern Wood-Pewee, and Cape May Warbler arrived today.
8 May: Quite sparrow-y today and yesterday, with increased numbers of White-throated Sparrows yesterday (gone today), White-crowned and Lincoln's Sparrows. Today the first Eastern Wood-Pewee and Cape May Warbler were seen on campus. There was also a report of a pair of Blue-winged Teals, uncommon on campus.
7 May: An adult Bald Eagle soared over campus today. New arrivals included Red-eyed Vireo and Swainson's Thrush, although in general it was much quieter than it has been for the last five days or so.
6 May: A Golden-winged Warbler was found today, as well as Great Crested Flycatcher, Indigo Buntings, and two Orange-crowned Warblers.
5 May: A Gray-cheeked Thrush was banded today, first for the season. Also new were Magnolia Warbler and Tennessee Warbler.
4 May: A Hooded Warbler was reported today, along with Ruby-throated Hummingbird and Northern Parula.
3 May: Continued birdy today, with new arrivals including Common Yellowthroat, Black-throated Blue Warbler, Warbling Vireo, and Chestnut-sided Warbler. A White-eyed Vireo was singing right next to the nets, but avoided capture.
2 May: A large influx of migrants produced only a few new species -- Blackburnian Warbler, Lincoln's Sparrow, and Wood Thrush -- but large numbers of many species and increased numbers of most.
1 May: The only new spring arrival today was Northern Waterthrush.
April 2006:
30 Apr: A spate of new arrivals hit town today. The best bird was probably an Orchard Oriole in east Dearborn. Baltimore Orioles were also reported, along with Rose-breasted Grosbeak, Ovenbird, Eastern Kingbird, Gray Catbird, and American Redstart (a new early date). Large numbers of White-throated Sparrows, Yellow-rumped, and Palm Warblers were also found.
27 Apr: A Spotted Sandpiper was a new arrival today, as was Blue-winged Warbler and Orange-crowned Warbler. There was an influx of Palm Warblers, with 7 seen on today's survey.
25 Apr: The first Nashville Warbler was seen in west Dearborn today.
23 Apr: There was an influx of White-throated Sparrows noted today, and three Blue-headed Vireos were new arrivals. A trio of Pine Warblers was also found, and Blue Jay migration continued, with over 75 seen this morning. Horned Larks have been recorded as flyovers the last two days.
22 Apr: A Least Flycatcher seen today was several days earlier than our earliest spring record, but one was also noted in Ontario. Black-throated Green Warbler was another new arrival on campus, and the first Black-and-white Warbler was in east Dearborn.
21 Apr: Blue Jay movement has started in earnest, with one flock of about 50 heading north being noted. Also four Broad-winged Hawks were seen kettling over campus.
20 Apr: The first House Wren of spring was singing today.
