Legend / Information about data

The Rombird database is focused mainly on the information collection related to rare bird species on national and regional level, respectively on collecting data about the appearance of scarce species or those considered to be interesting in Romania.

Out of this reason, the observations introduced in the database are categorized automatically and placed in the category appropriate for their status. Now they can be grouped in four categories, each of them having separate button for data visualization. These are: a) national rarities, b) regional rarities, c) interesting species and d) the possibility to filter all observations

  

The colors of the observation represent the status of the respective data, as follows:

bold red = rare or very rare species on national level (accidental species or with regular yearly appearance in a very small number, which description are obligatory to be reported to the RRC). These species usually have minimum 1 and maximum 50 observations in Romania.

red = rare species on national level (species with regular, yearly appearance but usually in small number, species with distribution restricted in small area of the country and invasion species). Such species have usually from several ten to several hundred records and no description necessarily to be report to the RRC. 

bold green = very rare or accidental species on regional level. These species can be common in some geographical regions of the country (e.g. Great White Pelican in Dobrogea or Bărăgan), being accidental in other regions, such as Transylvania. Thus, the observations in Dobrogea and Bărăgan will appear in black in the database and those from Transylvania will be with bold green.

green = rare or scarce species on regional level (here we find species with yearly or almost yearly appearance usually in relative small number or regular breeding species whose detectability is reduced, accordingly we have lack of data). 

black = other interesting observations (in this category we find less common, rather scarce species on national or regional level). 

grey = other observations (common and abundant nesting, migrating or wintering species which are ordinary in all geographical regions of the country).

 

Accessing the button National rarities only the data of very rare species on national and regional level and the data of the rare species on national level will become visible (the ones with bold red, red and bold green). The button National and regional rarities displays the observations of the very rare and rare species on national level and those of the rare or scarce species on regional level (bold red, red, bold green and green). Under the button Interesting observations will appear all the data mentioned above (from the superior categories) and other observations regarding to the less common species on national level.

Accessing the button All species record, besides those data mentioned above will be displayed the observations of the common and very common species too.

Due to the fact that some of the species appear more frequently and in higher number in some regions of the country, the observations of the same species will appear with different color according to the place of observation. Each species has a code for each county which code placing the observation depending on the status of the species (rare on national level, regional rarity, scarce and so on) to the corresponding category.

The data of the very rare, accidental species are the only that will appear with bold red regardless of the region where the bird was observed. The species considered to be rare on national level, such as Red Knot (Calidris canutus) or Bar-tailed Godwit (Limosa lapponica) appear with red in any region (each county), because are considered as rare throughout Romania. The Eastern Imperial Eagle (Aquila heliaca) appearing also relatively rare, but more regularly in Dobrogea and in Western Plain of Romania for which these data will appear in red in these areas and with bold green in all other regions. The case is similar with the Eurasian Dotterel (Charadrius morinellus) whose observations from Brăila County (where the species is a regular migrant) will appear with red, all others from other parts of the country will be bold green. It is noteworthy that the very rare and accidental species on regional level (bold green) have a superior status than those the rare ones on the national level (red). Some further examples for a better understanding of these categories: the appearance of a Dalmatian Pelican (Pelecanus crispus) or a Collared Pratincole (Glareola pratincola) in Maramureş County is considered to be more interesting than a record of a Velvet Scoter (Melanitta fusca) or a Slavonian Grebe (Podiceps auritus) anywhere in the country. 

Species like Red-necked Phalarope (Phalaropus lobatus) or Broad-billed sandpiper (Limicola falcinellus) appearing regularly and in significant number in Dobrogea having sporadic appearance and in reduced number within the country. For this reason this species’ data will be displayed in black (interesting observations) in the south-eastern part of the country (Dobrogea), and in green in Transylvania where they are considered rare or scarce species.

We encourage uploading of the observations regarding to very rare to rare species on national and regional level as well the observations concerning sporadic and interesting species. Beside these, those observations of the c ommon species’ occurrence in unusual periods of the year are also welcome (for example record of Black-crowned night heron in January, Greater white-fronted goose in July) as well as the data referring to unusually high numbers of some species (e.g. 200 Caspian Terns wherever in the country, 8000 Bramblings in a town park etc.).
