I am a lifelong naturalist in pursuit of contributing as much as possible to our understanding of the natural world, documenting everything that flowers, slithers, walks, swims and flies.

You can view videos of some of the observations submitted here on My YouTube Channel.

My enthusiasm for nature began at about age eight with a keen interest in arthropods, especially scarab beetles and other insects. Starting at age 13, I spent the next few summers assisting with the re-sorting of the Pennsylvania State University collection and leading public tours at the Frost Entomological Museum, eventually amassing my own 8,000 specimen collection. For the most part, I now "collect" specimens only through photography. I transitioned my interest primarily to ornithology in my later teens, later in life setting various Big Day/Month/Year records, starting a new CBC and leading dozens of public walks.

As an undergraduate at Penn State in the late 90s, I was employed with the Department of Agronomy and participated in various turfgrass research initiatives dealing with soil amendments, bentgrass morphogenesis, fungal resistance among others (see pubs below). This eventually led to a passion for Botany, especially Euphorbia, and frankly these days I am interested in almost everything!

A Note About Community ID

I have chosen to opt out of "Community ID" on the site. There are numerous reasons why I have chosen this setting for my observations, which I learned over the years of contributing here:

1) Sometimes after detailed analysis and review of keys for an organism, a user may select a more general ID on it. This can be correct or maybe it isn't, but this gives me the chance to review it for my own knowledge.

2) Occasionally there are spammers that become active on the site, and this allow some control over that.

3) This setting helps me take others' identifications more seriously and forces me to review each disagreement. If I agree, I will generally accept the ID. That said, if a user disagrees without explanation (especially with difficult-to-separate taxa), and I don't know you or maybe you haven't filled out your profile, I am not likely to agree just because you said it is what you feel it is. My ID accounts for something too. :-)

Finally, If I don't respond right away, understand I have MANY life pursuits away from iNat and I am generally stretched for time, so it may take me a while. Across my 46,000+ observations here, I need to use my time wisely. If you feel I have overlooked something, you can politely nudge me. Be respectful and put a brief note on it to help me understand your choice. I assure you that will go a long way.
