Blue-headed Vireos on the decline?

Drew WeberAnalysis, eBird, General News and InfoLeave a Comment

There has been a lot of talk on the PABirds listserv regarding a possible decline of Blue-headed Vireos based on the scarcity of individual sightings this fall. I decided to look into some eBird graphs to see if our collective eBirding can shed some light on the discussion. The graphs do have to be taken with a grain of salt … Read More

Next up- ducks

Drew WeberAnalysis, eBird, General News and InfoLeave a Comment

The next group of birds that will be moving into the area on their southbound migration are the ducks. There are already scattered reports of ducks across the state, but numbers should really increase over the next few weeks. Below are the eBird frequency graphs for the ducks, split into dabbling, diving and sea ducks. These graphs show the percentage … Read More

New eBird feature threatens to clog inboxes

Drew WeberBird Finding Tips, Birding, eBird, Listing, Rarities, Tutorial6 Comments

Just today as far as I can tell, eBird launched a new feature that threatens to clog my inbox. It’s not enough that they already send out emails of recently reported ABA rarities and birds reported in Pennsylvania that I still don’t have on my life list. Now, you can also subscribe to these alerts on the county level. This is huge … Read More

Birding resources online- Pennsylvania

Drew WeberBird Finding Tips, Bird News, Bird Websites, Birding, eBird, General News and InfoLeave a Comment

Pennsylvania is a great state to bird in; we have enough elevation change to afford us a large diversity of breeding and migrating warblers, we are well situated to observe a large and diverse raptor migration, and we have a large community of talented and helpful birders who are willing to share sightings and help others see good birds. Birding … Read More

County Listing

Drew WeberBirding, eBird, Listing, Maps and Directions4 Comments

Birders keep lists- life lists, year lists, state lists, birds on a wire list, birds seen from the sunroof- it’s one of the quirky things we birders do. The way I see it, these little games keep things interesting through the slow periods in the winter and mid-summer when birds are less vocal and little migration is happening. One ‘meta-list’ … Read More

eBird Tutorial- Merging personal locations to hotspots

Drew WebereBird, Nemesis Bird Podcast, Tutorial2 Comments

One of the cornerstones of the whole eBird system is the idea of hotspots. Hotspots allow people to submit sightings for a common location and this combined effort results in more accurate bar charts for that location. Seasonal distribution for species at hotspots can be calculated based on hundreds or even thousands of checklists rather than the few checklists that … Read More

I have been using several on my … Read More

More Shiloh Rd Rough-legged Hawks

Drew WeberAnalysis, Bird Sightings, Birding, distribution, eBird, Identification, PhotographyLeave a Comment

I stopped by the Shiloh Rd grasslands yesterday and a light morph roughleg was perched right in the interchange, oblivious to all the traffic around it. After a short scan of the extensive grasslands I only came up with one other roughleg, another light morph. This is the smallest number of roughlegs I have seen here in over a month … Read More

Pennsylvania eBird comparison

Drew WeberAnalysis, eBird2 Comments

After posting the graphs of eBird submissions in Centre County I ran through the View and Explore Data part of eBird and did the same thing for Pennsylvania. The comparison is interesting because it shows that quite a few people across the state have kept detailed lists and entered these historical sightings back at least several decades. If anyone has been … Read More
