Bobolink (Dolichonyx oryzivorus)

Abundance: Uncommon during spring; Very Uncommon during fall; Occasional during early summer and early winter; recorded in 22 Regional counties (Map of UCR Distribution); data from the Regional bird-monitoring efforts are inadequate to determine a trend in the population migrating through the Region and even more inadequate to determine a trend in the very small possible Regional breeding population (see also Regional Bird-Monitoring Plan).

Status: Transient during spring and fall; Visitor (and possible Summer Resident) during summer (1 record); and Visitor during winter (1 record); photograph (see above).

Regional High Count and SBC/SBB High Count: 86 (3 May 2011; White County, Tennessee [SBC]; m. ob.); FBC/FBB High Count: 13 (25 September 2004; White County, Tennessee [FBC]; m. ob.).

Out-of-Season (Summer) Records:

9/11 June 2010 (2—singing and displaying males/4—3 singing and displaying males and 1 probable female) Cummings-McWilliams Rd., Pulaski County, Kentucky (Stephen J. Stedman/Roseanna M. Denton), a Pulaski County Foray record on the former date; the field where these males were displaying had been cut by 19 June 2010 when no Bobolinks could be located (Roseanna M. Denton).

Out-of-Season (Winter) Records:

20–28 December 2003 (1—basic male) Ironwood Golf Course, Putnam County, Tennessee (Michael J. Hawkins, Kenneth L. Morgan, Ginger K. Ensor, Stephen J. Stedman photo [25 December 2003]; Hawkins et al. 2005), a CBC record.

Regional Extreme Dates:

    Spring: x (

    Fall: x (

    Note: Spring arrival is generally widespread by 5 May, while spring departure is usually complete by 15 May although the data for spring departure dates are quite thin; dates for widespread fall arrival and fairly complete fall departure are difficult to estimate because fall data are quite thin.  Regional dates of earliest reported spring arrival and latest reported spring departure, as well as earliest reported fall arrival and latest reported fall departure, for the migration seasons 20022011 follow:

Year Early Spring Arrival Date Late Spring Departure Date Early Fall Arrival Date Late Fall Departure Date
2002 27 April 21 May 11 September 25 September
2003 1 May 24 May -- 20 September
2004 2 May -- 31 August 9 October
2005 22 April -- -- --
2006 29 April 20 May -- --
2007 28 April -- -- 15 September
2008 3 May 15 May -- 4 October
2009 2 May 11 May -- --
2010 26 April -- -- 27 September
2011 30 April -- 4 September 17 September

Breeding: Possible (Recent). Courtship displays were observed in one block during Pulaski County Foray 9 and 11 June 2010 (see Out-of-Season (Summer) Records [above]).

Habitat: Weedy fields; fields with some types of densely planted agricultural crops.

YardWatch Results 2003 and 2004: Registered on 0 (of 125) monthly check-lists during 2003 and on 1 (of 206) check-list during 2004, leading to a YardWatch frequency classification of Rare during the latter year; this YardWatch frequency classification is inconsistent with the overall Regional abundance classification.

* Because some foray blocks fall into two or three counties, the total of blocks in the Kentucky or Tennessee portions of the Region is less than the sum of the blocks in the counties of each portion of the Region; similarly, because some blocks fall into both states, the total of blocks for the Region is less than the sum of the blocks in the two states.

Check-lists of Birds for the Counties of the UCR

Check-lists of the birds of each county of the Upper Cumberland Region may be viewed by clicking on the links below. For each county, there are two check-lists: one list that shows the species that have been observed and where possible documented in the county within the larger list for the entire Region; and one list that includes only the species observed in the county with annotations for the date and observers for at least one sighting (the ultimate goal of the latter list will be to include annotations for the very first known Regional observation of each species in that county; this goal is probably one that will take many years to complete, if completion is even a possibility). To see if the species discussed in this species account has been observed in a county, click below or click on the link for the Map of UCR Distribution near the top of the page.
