arctica and Pacific Loons are now considered distinct species (Auk 106:680-686, 1965), differing mainly in the gloss of the blackish throat patch. Hypothetical. One was identified on 12 and at Whitefish Point (Chippewa County) (MAS AB 37:872, 1983), another at the same site on, well-described at the time (AB 38:913, 1984 MORC), but Arctic Loons G.A few recorded into summer (JPW 44:51, 1966). Most sightings and specimens were on the Great Lakes in spring or autumn. Further field work likely will confirm their occurrence with good photographs or museum specimens. Several of these are reasonable identifications and are supported by detailed written field descriptions. "Hypotheticals" are those species reported only as sight records but not documented with specimens or photographs. The details of seasonal occurrence are available in the seasonal summaries of the Jack-Pine Warbler, Wood (1951), The Goldeneye and annual Field Notes of the Berrien Audubon Society, and Mlodinow (1984). "Irruptive" birds occur in large numbers in some years and usually few or none in other years these are mainly wintering visitors from the northern coniferous forests. "Irregular" birds are seen in some years but not in others. "Regular" birds are seen every year or nearly every year. "Summer resident" indicates that the species occurs in Michigan during the breeding season and that most or all individuals migrate out of the state during the colder time of year. "Transient" indicates that the species occurs in migration, but unless noted otherwise it does not nest in the state. common, regularly occurring in the state in numbers in every year in suitable habitat.Įstimates of population numbers of breeding birds are included where available, as are the migration routes and wintering areas determined from recoveries of banded birds. uncommon, sparse population but usually seen in every year.vagrant, one to four records for the state.The categories used to describe status are: Hypothetical. Indicates those birds not represented by specimens, recognizable photographs, tape recordings, or verified banding recoveries.Introduced birds and exotics are included only if they have established breeding populations. The list includes the migratory and breeding status of Michigan birds and the seasons of occurrence and their regularity and abundance. Subspecies names are included only where they differ from those used in works cited in Payne (1983). Names follow the American Ornithologists' Union (1983). Choose large format, entire state Lower Peninsula Upper Peninsula (these last two will fit on one page when printed). Field observations have not been accepted for the first record of a species in Michigan, unless accompanied by a recognizable photograph or tape recording.įig. Most have not been accompanied by adequate detailed descriptions made at the time of sighting in the field. Most recent information on birds in Michigan is from field observations.Ī number of interesting new distributional records have been reported in recent years. In recent years the biology and distribution of birds have increasingly been determined with field observations, and museum collecting is done only under special circumstances. Museum specimens are the primary sources of information about bird species, and they are the original reference material used in distributional works and field guides. I have accepted only the birds known in the past or at the present time from these permanent reference sources. Used with one of the popular field guides to North American birds, the checklist should be helpful in identifying birds in the field in Michigan.Īll species known to occur in the state and documented with specimens, photographs, or tape recordings are included in the checklist. This checklist is a summary of the occurrence, breeding status, migration, and distribution of birds in Michigan. Please note: for updates on rare species, name changes, or new additions to the list, please see the Michigan Bird Records Committee web page INTRODUCTION of Michigan Museum of Zoology Miscellaneous Publication no.
