Boone County Migratory Bird Count Results- May 8, 2021

by John Besser

The Covid-19 pandemic has affected just about everything Columbia Audubon Society  has done over  the past year, but we have fought to maintain some of our traditions, including the Boone County-wide bird count held on the traditional ‘Big Day’, the second Saturday in May.

Our ability to conduct this count during the pandemic has a lot to do with the availability of eBird, which allows numerous teams of socially-distanced birders to share their checklists with the chapter’s eBird database, ‘casbirddata’. Once the data is in this account, it is pretty simple to download all the data for the count day and tally up the species and total numbers of birds seen countywide or in each count areas. Now that the count data is compiled, CAS has our own archived digital version of the data, and all the data is still available to Ebird users,.

Table 1. Summarizes the results of the 2021 count. We received 92 checklists from 14 count areas, representing 141 party-hours in the field. Our species total was 183, with a total count of almost 19,000 birds.

The most impressive feature of the species list is undoubtedly the 30 Warbler species, which includes species that often seen in central Missouri, including Cape May Warbler, Connecticut Warbler, and Swainson’s warbler. Also impressive were the 13 species of shorebird and 11 species each of waterfowl, sparrows and flycatchers. On the other hand, it’s disappointing to see only a single Eastern Whip-poor-will reported from Boone County.

The number of species observed in each county area varied widely depending on quality of habitat in the level of count efforts. The two areas of the highest species count were 10A, which includes Eagle Bluffs (135 species), and area (117 species), which includes most of the heavily birded City of Columbia. I’ve attached a spreadsheet that lists the species seen in each of the count areas.  So check out the total for your area, and think about what species may have been missed and where to find them during the next Boone County migration count!

Thanks to all the volunteers who helped make this count happen

CAS Board Meeting Highlights for March 16, 2021

by Douglas Miller

Upon review and board approval, final meeting minutes are posted to the Minutes page. Following are highlights of the unapproved minutes from the last meeting:

Nominating Committee

  • Brooke Widmar reports that no additional nominations for Director have been received. An e-mail election will be held in April. Brooke will create a Google form for members to cast their vote; notice of the procedure will be in the next Chat.


  • Shelby Thomas reports that so far there have been no responses to the proposed revised membership levels. On a related note, the Bylaws committee is considering instituting an honorary membership that does not include the right to cast votes; also possibly specifying that a “Family” membership would include exactly two votes. Considering the previous Family level was twice the Individual level minus a discount, a revised Family amount might be somewhere in the $40–$45 range.

Nature Areas

  • Bill Mees reports John Besser and Jim Gast met with deputy sheriff Eli Norwood at Wild Haven to discuss vandalism. (The plexiglass pin board was damaged, in addition to the other incidents of theft and vandalism in the past.) Recommendations included (solar) motion-activated lights, “no trespassing” signs, and encouraging more public visitation. Bill’s contact number has been given to the police dispatcher to help keep us more easily informed of suspicious activity at the nature area.
  • Bill has called the Missouri One Call System in preparation for beginning the parking area project at Wild Haven. Another work session has been scheduled to continue burning brush piles and to pick up litter.
  • Bill reports a meeting with Mike Snyder of Columbia Parks & Recreation, Allison Vaughn, Jim Gast and John Besser regarding prescribed fire at Bonnie View and CANS. Parks is in favor of a fire project; they’re looking for a contractor to conduct the burn on both park and CAS property. We’re targeting a burn in November or December 2021.
  • Bill reports that hardware for the CANS interpretive panel has arrived. Jim Gast, John Besser and Allison Vaughn approved the installation site. The panel design is complete; all photos were from CAS members.
  • Bill and Mike Szydlowski (Columbia Public Schools science coordinator) spoke with a Fairview Elementary 3rd grade class about their plans to create a prairie.
  • A Mizzou journalism student conducted an interview with Bill at CANS that resulted in a 90-second “audio postcard” broadcast on KBIA.
  • Bill is proposing a new Wild Haven sign to replace the old one, possibly constructed of cedar boards with cut-out letters screwed on, affixed to two posts; such a design could cost as much as $400 in materials. The placement of the new sign is still being contemplated.

Outreach and Education

  • Lottie Bushmann will escort a Cub Scout pack to CANS one evening in April.
  • Jim Gast will be presenting a program for the Centralia Garden Club.
  • Lottie has not yet met with Mike regarding possible alternatives to Hog Island for teacher education.


  • Brooke Widmar reports the Prescribed Fire legislation has passed through hearings in the Missouri House and Senate; it’s being prepared for a floor vote.
  • Another pending bill, HJR55, would modify the structure of the Missouri Conservation Commission. Bill Mees asked if there was a consensus that CAS should go on the record opposing the legislation. There was. Brooke will monitor the bill; we will have a statement prepared for local representatives in case the proposed legislation successfully passes out of committee.

The board approves that CAS publicly oppose HJR55.

Canton Subdivision

  • Jim Gast reports on a proposed high-intensity 65-acre development of 113 homes next to Rock Bridge Memorial Park. This location borders the Gans Creek Wild Area, separated only by the oil/gas pipelines. Nancy Bedan suggests that CAS come out on record opposing the proposal and designate representatives to testify at city meetings. Jim Gast will draft talking points for the board to review; Jim and/or Brooke will represent CAS at city meetings; the talking points will go into the April chat to encourage members to contact city representatives.

The board approves CAS opposing the Canton Subdivision project as currently proposed.

Spring Missouri Birding Society meeting

  • Lottie Bushmann reports on upcoming joint CAS/MBS field trips as part of the MBS spring meeting in late April and early May. These will be socially-distanced, masked, small groups at Rock Bridge Memorial Park. Doug Tallamy will present a program about native plants as part of the main MBS meeting.

Sponsoring Noah Strycker

  • Nancy reports on an event that CAS might help sponsor: a talk by noted birder Noah Strycker at a Mizzou Botanic Garden event in October. The program would be free and open to the public. Nancy proposes using up to $500 of the CoMoGives windfall to help underwrite the event; the Missouri Birding Society may also provide funding. In exchange for the financial support, we are asking for prominent mention as a sponsor. It is hoped such a sponsorship will provide greater exposure and forge stronger connections to people associated with Mizzou. The event is still in the early stages of planning, and MBG has not requested a specific amount.

The board approves providing up to $500 to support the Mizzou Botanic Garden event, on the understanding that our sponsorship would be highly visible.

2021–2022 Budget

  • Jim Gast reports that he and Eric Seaman are working on next year’s CAS budget. They are requesting that board members submit any proposed changes before the April board meeting. The budget will be approved at the May board meeting.
