Dear colleagues,
I am conducting a literature search on the application of species distribution modelling techniques to avian invaders, to see how frequently and for what purposes these modelling techniques are used in the context of invasive birds.
Semi-systematic searches on Google Scholar and Web of Science resulted in a preliminary list of publications (accessible here, full link below). So far, I found 22 studies that cover in total about 40 different invasive bird species.
This is less than I had intuitively anticipated, and I’d like to ask you whether you could notify me of any publication that I may have missed (either by adding them to the Google Sheet, in the comments sections below or via e-mail: [email protected]).
For clarity: with species distributions models [SDM, also known as Ecological Niche Models ENM, sometimes also called bioclimatic envelope models, or habitat suitability models], I mean a family of correlational, statistical techniques that use species occurrence data and spatial environmental data to model species distributions. All applications involving invasive birds are of interest to me.
Many thanks in advance,
Best wishes,
Diederik

Hi! You should include this paper:
S. Herrando, F. Llimona, L. Brotons, and J. Quesada. 2010. A new exotic bird in Europe: recent spread and potential range of Red-billed Leiothrix Leiothrix lutea in Catalonia (northeast Iberian Peninsula). Bird Study 57 (2):226-235.
One fundamental assumption of very many of the regressive and correlative approaches is that of 'equilibrium' i.e. that occupancy of a cell across the study extent describes a niche suitable for the species, and that absence describes an unsuitable one - which can only be determined as a consequence of a population attempting to have persisted there and failed - i.e. you have to know that your study species is at equilibrium with the extent
Invasives - by definition break that assumption and regressive models cannot be recommended for them - has not stopped the enormous literature on the subject but what do you expect when you put a complex black box technique into an easy to use computer package with a bunch of abstract parameters critical to analysis set with default values (e.g. Maxent) - people put data in and get a pretty map out - what can be wrong with that!
Couple that with the very well described lack of spatial and temporal transferability of many correlative models and it may be less surprising that such statistical approaches have not been used extensively - mechanistic niche approaches (e.g. bioclim) are obviously different
