![]() ![]() I looked at 39 countries across Europe and came up with a set of statistics to help us understand settlement patterns in a more nuanced way. That's why I set out to understand the topic in more depth, using alternative measures of population density. The same is true of Australia, Canada and other large, highly urbanised nations. The figures will tell you density is very low (eight people per km²) but this it not what most people in Russia experience in their daily lives. Consider a country such as Russia, where urban density is high, but there are vast swathes of empty land. Yet simply dividing the number of people by the land area of a country is not always the best way to understand population density. ![]() But it's not as densely populated as the Netherlands, where there were 505 people per km², or a much poorer country such as Bangladesh, where there were 1,252 per km². With continuing help and participation from birders throughout the state, this exceptional, and unique to Idaho, resource will represent a more and more complete picture of Idaho’s avifauna.With 426 people per km², as of 2016, England is densely populated when compared to most other European countries. Report all other species using the Latilong Status Change Form.Report species on the List of Idaho Review Species with the Rare Bird Report Form.eBird checklists fill in some of the gaps, however certain Latilongs are still under-birded and under-covered in the records, in some cases even for the presence of common species. Status change reports are particularly needed to document breeding and overwintering.One person can make a significant contribution! Compare your sightings with the species’ Latilong status on the maps and report any that will update the records.The maps are a product of decades of dedicated effort, but there is more to be done. Reports of sightings from birders are a critical component of the always on-going process of documenting Idaho’s bird distribution and population trends. The current maps are designed by Darren Clark, and Shirley keeps the species’ Latilong status up to date.īirders’ Role in Documenting Idaho Bird Distribution The species distribution maps were converted to digital form for the first time, presenting this vast amount of data to the wider birding community in a more accessible, and dynamically updated format. In 2006 Shirley collaborated with Stacy Peterson and the late Harry Kreuger to create an on-line version of Idaho Bird Distribution that appeared on the original Idaho Birds website. Search the Idaho Bird Records Database Species Distribution Maps You can read more about historical records and history of the Latilong study in the excerpts from the book. The database has grown from about 38,000 individual bird records when the 1998 edition of the book was published, to over 180,000 records. These records are contained in a database maintained by Shirley and Keith Sturts that has been continuously updated with Idaho sightings and reports, including IBRC rare bird records, status change submissions, NAB reports, and more recently, validated eBird records. Burleigh’s 1972 Birds of Idaho, many records from government reports and publications, ornithological collections of various museums, and thousands of reports sent in from birders around the state, formed the basis for the maps in the 1991, first edition of Idaho Bird Distribution. Records they collected, data from Thomas D. Mapping Idaho bird distribution by Latilong began with the 1980-1983 Idaho Bird Distribution Latilong Study by Robert Kuntz and John Doremus (Bureau of Land Management, Boise District). Fish and Wildlife Service, to give researchers consistent, unchanging units for long-term studies. They are used in biogeographic studies, like the Breeding Bird Survey of the U.S. Latilongs are rectangular areas drawn by lines of latitude and longitude. The book presented seasonal distribution maps for all bird species that were known to have occurred in the state, divided into geographical sections called Latilongs. Sturts, published by the Idaho Museum of Natural History and the Non-game and Endangered Wildlife Program of the Idaho Department of Fish and Game. The Distribution section of Idaho Birds is an on-line extension of the 1998 book Idaho Bird Distribution, Mapping by Latilong by Dan A. ![]()
