January 23 Field Trip Report



Ken led a group of eight bird-watchers around the Muskegon County Wastewater properties and the Muskegon Lake Nature Preserve today.  Thick frost covered everything at the Wastewater as did ground fog early on.  Some of these pictures might make it look cold, but it was colder.

Birds of note among our 26 species included 8 Bald Eagles, a Red-shouldered Hawk, 2 Common Ravens, 3 Golden-crowned Kinglets, an Eastern Bluebird, several Snow Buntings, and 3 Rough-legged Hawks including this one fanning its tail at us as we departed.

- NOON -

An hour at the preserve gave us 17 species, mostly duplicates of those at the Wastewater, but also the Eastern Towhee who's spending his winter here, and this Fox Sparrow who may be doing the same.

As Carol filled the feeders near the pavilion, flocks arrived including this American Tree Sparrow wearing jewelry by Brian, and Northern Cardinals of both sexes.

We concluded our day with lunch at Bernie O's in North Muskegon.

Brian's December Wastewater CBC Report

The 2015 Muskegon Wastewater Christmas Bird Count (CBC) was conducted on Wednesday, December 16. This was the eleventh consecutive year that we have participated with the official CBC program (coordinated by the National Audubon Society), although results have been submitted to Michigan Audubon since 2000. The designated count circle (15 miles in diameter) mostly encompasses private farmland and woodlots, but it also includes large tracts of public land managed by the Muskegon State Game Area (MSGA) and the Muskegon Wastewater System (MWS). Most birding is accomplished by cruising roads, although MSGA offers lengthy hiking jaunts.

The following ten volunteers, separated among seven parties, assisted with this year's effort: Dayle Vanderwier and Connie Peoples (in the WNW zone), Feller DeWitt (NNW zone), Ric Pedler and Jim Zervos (NNE zone), Charlie DeWitt (ESE zone), Jill Henemyer and Ken Sherburn (at MWS), Marc Miedema (at MWS), and Brian Johnson (at MSGA). Combined, observers accrued 27.5 hours (7.0 on foot, 20.75 by car) and 248 miles (7.4 on foot, 241 by car) of coverage.

Because the weeks preceding the 2015 CBC were accompanied by a strong El NiƱo weather pattern, temperatures in September, October, November, and especially December were warmer than normal. The daily mean of 45° on December 16 tied the highest in the history of the Wastewater CBC. Consequently, all creeks and ponds were devoid of ice, and no snow had covered the ground since November. In fact, only 3.9 inches of snow had fallen thus far this season. Unfortunately, winds were strong on count day, and the 2015 CBC ranks as the second windiest in its history. Skies were overcast all day, and rain fell in the afternoon. Cone crops were essentially absent this fall.

A total of 9,909 individuals, representing 49 species, was recorded on this year's CBC. Total individuals and species both fell below the historical (2000-14) means of 10,842 birds of 55 species.

Ice-free conditions and diligent work by Jill and Ken at the MWS lagoons significantly boosted numbers this year. The total of 7,878 waterbirds, representing thirteen species, was 3,000 birds above average and ranks as the fifth highest since the inception of the count. Moreover, waterbirds comprised 80% of all birds seen this year, and that ratio represents the greatest imbalance in the history of the Wastewater CBC. Bufflehead and Ruddy Duck established new high totals, and the 72 Hooded Mergansers completely annihilated the old record of just two! The Shoveler total of 2,447 was a great winter tally for Michigan, and an Eared Grebe was a Wastewater CBC first.

Raptors were relatively scarce this year. Rough-legged Hawks were missed for the first time ever, but a Peregrine Falcon on the center dike was a nice find. Two Snowy Owls were the only owls encountered.

Due in part to weather conditions on count day, landbird numbers were dismal this year. Not only do strong winds reduce landbird activity in general, but they also severely hinder aural and visual detections. The dreary skies and afternoon rain certainly did not help matters. Moreover, sparse food crops and mild fall weather drastically curtailed numbers of winter visitors. Lingering summering residents were very scarce due to a combination of low breeding productivity, reduced berry crops, and dispersed forage and habitat availability stemming from milder weather.

The only regular landbirds more plentiful than usual were Hairy Woodpecker, Pileated Woodpecker, and Golden-crowned Kinglet. Conversely, Horned Lark, Red-breasted Nuthatch, Cedar Waxwing, Snow Bunting, and Song Sparrow were missed entirely. Local Turkey counts remain below their peak from the mid-2000s. Depressingly, Ruffed Grouse, common across Muskegon County three decades ago, seem to have all but disappeared locally
Not surprisingly, numbers of irruptive finches were abysmal, though a single Purple Finch was encountered at MSGA. As was the case at the Muskegon Lake banding station this fall, goldfinches were likewise scarce. On the other hand, one Northern Shrike, one Common Raven, and eight Yellow-rumped Warblers (at MSGA) were welcome finds. An Eastern Meadowlark (at MWS) represented the first for the Wastewater CBC.

Of the species recorded this year, 27 exhibited totals below previous historical means, whereas 22 exceeded those averages. Six species set or matched record high counts. The four most abundant species (Shoveler, Herring Gull, Canada Goose, Mallard, and Starling), comprised 74% of all birds seen. Two new species* recorded on the 2015 CBC raised our cumulative total to 111.
Despite the relatively few landbirds and sub-optimal weather conditions, unusually warm temperatures, a pleasant lunch, and several nice birds provided yet another enjoyable CBC.
