R & E (1992): Except during years when there is a major invasion, birds are initially observed about mid-Oct.
In falls where there is a large influx (like the falls of 1966, 1972, 1976), birds are seen as early as mid-Sept.
During "average" years, the largest numbers are not encountered until late Nov. and early Dec.

Aug. 5, 1996 - Ties earliest fall record

This was part of a major movement of Rocky Mountain crossbills (bendirei, other races?) to the Midwest that began in July.

Nov. 26, 1969 - Highest fall single day count
(61); 10 miles west of Maryville, Nodaway Co.; David Easterla; R & E.

26th Annual MBRC Report, 2013-32. In recent years it has been recognized that there are a number of different populations of
Red Crossbill whose flight calls are characteristic and can be identified by analysis of a spectrogram produced from an audio
recording. It may be that some of these populations are reproductively isolated and thus should be considered separate species.
At this point the best course is to record the calls when possible, determine the type, and archive the information for future reference.
So far nearly all Red Crossbills occurring in Missouri, when vocally analyzed, have been of Types 2 and 3. During the crossbill
invasion year of 2012-13, however, this individual was recorded and its calls analyzed by Matt Young of Cornell University,
who determined that it was a Type 5, a type known to have occurred very few times in the eastern U.S.

Dec. 8, 1965
(Female of small-billed race); specimen (NWMSU, DAE 1042); 10 miles west of Maryville, Nodaway Co.; David Easterla; R & E.

Dec. - Jan. 1981-82 - Highest count
(up to 200); Columbia, Boone Co.; Sherman Sutter; R & E, BB 49[2]:17.

Dec. 27, 1955 - High count
(60); Parkville, Platte Co.; Ben King; R & E, AFN 10:255.

Dec. 30, 1973
(Male of small-billed race); Specimen (NWMSU, DLD 168); Maryville, Nodaway Co.; R & E.

R & E (1992): Following winters where there has been influx, birds are regularly seen until mid-April and casually into May.

May 15-30, 1982 - Late
(2 - 15); Columbia, Boone Co.; fide Sherman Sutter; R & E, BB 49[3]:23.

May 27, 1951 - Late
(Number not listed); Kansas City, Jackson Co.; D. Hall; R & E, BB 52[3]:16.

R & E (1992): Late lingering birds should be carefully watched for signs of breeding.

R & E (1992): The vast majority of the birds that appear in Missouri are relatively large-billed and have been assigned to the race, L. c. bendirei.

Note: Any significant observations since R & E will be added at a later time.
