How the California year breaks down
Counted, not claimed
Of the 24 species, 12 are with you all year in California, 7 move only a short distance, and 5 leave the continent and come back.
California's fullest month is May, when 24 of them are reliably about; the quietest is January with 12. The presence chart shows every month for every species.

Before you buy
Who this is for
Made for
- Beginners who want to know which California birds they are actually likely to see
- Feeder watchers and walkers keeping a list
- Anyone teaching a child to notice what is out there
Not for
- Experienced birders after a full California state checklist — this is the consistently-seen species, not every rarity
Everything here describes typical timing across California, drawn from long-run records — weather, elevation and how close you are to water all move the real dates around. So the California pages say "usually early May" and never "May 4th", which is not hedging but the most the data can honestly carry.
Where it comes from
Compiled from
USGS Breeding Bird Survey · State fish & wildlife agencies. How each of these is used in the California edition, and which figures are measured rather than modeled, is set out in the methodology.
Questions
Before you decide
Is this specific to California, or a national guide with the name swapped in?
It is built from California's own data. The species list is the one recorded on California survey routes, ranked by how consistently each turns up — 24 species in this edition.
Where does the California species list come from?
It is drawn from the USGS Breeding Bird Survey routes that run through California, ranked by how consistently each species is recorded.
How accurate is the timing for California?
It describes typical timing across California drawn from long-run records, and because weather, elevation and habitat move real California dates around it says "usually early May" rather than "May 4th".
Is it worth paying when the California pages here are free?
The free California pages are the month you are in; this is the whole California year, planned before it arrives and printable, so you are not holding a screen in the garden.
Will it work for my part of California, or just the big cities?
It is written at state resolution — California as a whole, with regional notes where California genuinely differs end to end, and nothing behind it is recorded finely enough to honestly promise more than that.
What format is the California edition, and can I print it?
A PDF laid out for both Letter and A4, one page per sheet — printing it is the point, since the California pages are made to be carried outside.
What if the California guide is not what I expected?
Email hello@birchcompass.com within 30 days for a full refund on the California edition, and keep the files either way — asking for them back would be theatre.
