Birders have tons of festivals, seemingly across many geographies and months of the year. These events are often 2-4 days, and full of seminars, field trips, and other activities. These events often draw people from large areas (like entire US states, or sometimes across the country and beyond). Are there similar events but with a broader naturalist slant?
I’ve seen a few birding festivals tack on “…and nature”, but they seem to still be 80% birding.
I don’t know if this counts as a festival, but the conservation districts, forest preserves, ect, in my state go to a conference every year where all manner of conservation subjects are discussed like:
Archeology, natural land divisions, nesting birds, reptile diseases, new invasive species, bees and so on. One year there was even a workshop on using iNat to log what is on the properties.
We have a Butterfly Festival in South Texas the week before the Birding Festival. In October/November. A really good time of year for both. Many of those attending are into other areas of nature. I setup my moth sheet for both festivals last year.
Many parks or conservation areas with sufficient amounts of birders and birds host owl prowls, where you are guided through the forest with a group at night to see owls, and sometimes other night critters if your lucky. The Great-Horned Owls are always a treat!
