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

Centre County, PA eBird

On the power of submitting more to eBird

Drew WebereBird, Science2 Comments

Tim Schreckengost and I spent several hours this morning walking around Toftrees in search of sparrows and any lingering birds that hadn’t been scared south by the snow. I try not to set expectations too high on a cold, snowy morning like today as so was pretty happy with the 28 species we saw. We saw lots of sparrows- American … Read More

Grasshopper Sparrow abundances

Drew WebereBird3 Comments

eBird has just started releasing some really neat animations of the abundances of birds throughout the year. They have been giving some supercomputer processor time to analyze the millions of data points that birders have submitted across the US. One thing that really jumped out at me when I first saw this animation is how low the densities are in … Read More

Expansion of Eurasian Collared-Doves in the US

Drew WebereBird, Ranges and Distributions, Science1 Comment

On his Notes from Soggy Bottom blog, Bill Pulliam just posted a fascinating visualization of the spread of Eurasian Collared-Doves in the last couple decades. Using data from eBird, he compiled this animation of the range expansion between 1984 and 2010. The expansion is really quite impressive during the last ten years. One important thing to point out about the … Read More

Pintail parade

Drew WeberBird Sightings, eBird, Missed Birds1 Comment

Octorara Lake has been a great spot to see Northern Pintails this year. The last time I checked the area off of Mt Eden Rd, there were probably close to one thousand pintails feeding there. I was looking for a previously reported Eurasian Wigeon but struck out on that.  Eurasian Wigeons have made quite a showing in PA this year, … Read More

Olive-sided Flycatcher

Drew WeberBird Sightings, eBird, MigrationLeave a Comment

The highlight of a mornings walk around Lancaster County Central Park was the Olive-sided Flycatcher I found perched at the tippy top of a tree. I did not have my camera along so I took some shots with my phone, through by binoculars- phonescoping! They didn’t turn out amazing but you can see the vest like coloring of the chest. … Read More

Snow Geese flock, originally uploaded by topherous. Cornell Lab of Ornithology’s eBird site has just posted Bird Counting 101. For anyone who spends time out in the field watching large flocks, whether they are shorebirds, waterfowl or hawks knows that estimating flock size can be ridiculously hard. Just looking at the flock of Snow Geese above is overwhelming if you … Read More

The Christmas Post

Drew WebereBird, General News and Info1 Comment

Now that Christmas is officially over I feel as if I should past what I got today. Highlights include a brand new eastern edition of Sibley’s, a tiny little camera case, an awesome Mountain Hardwear down vest, and some clothes. But the most exciting present of all was a year’s subscription to Birds of North America (BNA) Online from Cornell … Read More
