Dear Jeff,
?
I sort of keep a list of species found nesting. Using AviSys, it is easy to list just about anything. I make up "Attribute Codes" for things I think are interesting, if AviSys doesn't already have one already. So, for example, there is already a pre-loaded attribute ("n") for?nesting. On the other hand, I had to make up my own codes for leucism and albinism.
?
There is a catch to using AviSys for listing nesting species. Most birders who use this code, I would guess, would enter "n" for birds that they saw carrying nesting materials, disappearing into a mass of vegetation, and so forth. For example, I know I've never found a nest of a Brewer's Blackbird, but I have found them repeatedly?carrying grass into small clumps of brush, so I know they were constructing a nest?in there. One would have to be purposeful right from the start, and use a specific code only in cases where the actual nest were seen, if one wished to list the number of species for which?one had actually seen a nest.
?
I just spent about twenty minutes examining my records. I had to list all my sightings in AviSys for which I had the "n" code. The vast majority were just for birds for which I could confirm nesting, even though no nest was seen--carrying food to cheeping young that I couldn't see, repeatedly carrying twigs into a nest I could not see, and so forth.
?
After ticking off the ones where I actuall ysaw the nest, I came up with 113 species, worldwide! Thanks for getting me thinking of this! Now I need an aspirin--writer's cramp!
?
Yours truly,

"Nun," sagte ich, "wenn ich ein Taugenichts bin, so ist's gut, so will ich in die Welt gehen, und mein Glueck machen." Und eigentlich war mir das recht lieb, denn es war mir kurz vorher selber eingefallen, auf Reisen zu gehen, da ich die Goldammer, welche im Herbst und Winter immer betruebt an unserm Fenster sang: "Bauer, miet' mich, Bauer, miet' mich!" nun in der schoenen Fruehlingszeit wieder ganz stolz und lustig vom Baume rufen hoerte: "Bauer, behalt' deinen Dienst!"
