This remarkable bird uses songs of other Michigan and attributed at least some of the bird species and non-bird species and even reports to escaped caged birds. Wood (1951) copies sounds of mechanical devices like mentioned a total of seven nest records between telephones and sirens. Historically, the bird was 1910 and 1934, all in the SLP in counties which captured and caged for this very ability and have records in both Atlases and most other many early records in Michigan were historical accounts (Zimmerman and Van Tyne discounted as being attributed to escaped pets 1959, Payne 1983). Zimmerman and Van Tyne (Sprunt 1948, Barrows 1912). (1959) added records from Clare and Cheboygan Counties in the NLP.

Most of these newly added only casually north of a line drawn west across counties were in the NLP and the western UP. the U.S. from the southern half of Michigan. Binford’s records of Northern Mockingbird There are scattered reports of the species nests in the Keweenaw Peninsula in 2005 and breeding as far north as Alaska (Sibley 2000, 2006 are the northernmost nesting records for National Geographic Society 2002). It nests as the species in the state and the first ever for that far south as southern Mexico (Derrickson and region of the UP (Binford 2006). Statewide, Breitwisch 1992). In Michigan it is a rare but most of the birds recorded during both Atlas regular breeder in the southern and western part periods were in the fruit producing areas in the of the LP and rare but regular during the southwestern part of the state and the counties breeding season in the UP (Binford 2006, around Grand Traverse Bay. Southeastern Hickman 2008). Except for one 1954 record of a counties in the lower two tiers and southwestern bird wintering at a feeder in Marquette, in late counties in the lower three tiers have the most winter the Northern Mockingbird is found only records.

Despite being at the northern edge of its range, Michigan Northern Conservation Needs Mockingbird populations seem to be expanding Because the Northern Mockingbird is at its slightly in both the LP and UP. northern range limit in Michigan, populations will likely continue to be small and there are no Breeding Biology current specific management plans for this Most Mockingbirds in Michigan are migratory species. However, documentation of its range though a few are always found on Christmas expansion by Binford (2006) and others calls for Bird Counts (NAS 2009). Successful nesters careful observation and reporting of all who do migrate tend to return to their previous potentially nesting individuals, especially those years’ breeding territory and re-pair (Derrickson in the UP. and Breitwisch 1992).
