Frames are every 1/2 hour for reflectivity and velocity, and every hour for the regional composite. Click on the thumbnail to view the full-sized animation.

As you can see from the composite image, migration was heaviest around the northeastern US and down around the Great Lakes, where southerly winds were strongest along the edge of the approaching cold front. Still, with clear skies and light winds over our area, Zugunruhe got the better of many birds that may have otherwise waited out better conditions just a weeks ago. Such are the patters of spring!

With no weather in the forecast to concentrate birds, but with light west winds over the state, I think the best bets for today will be inland migrant traps (Garret Mountain being my favorite) and coastal locations such as Sandy Hook. Of course, the best opportunity for diversity will be in south Jersey, and with the influx of birds apparent on the radar, we should see some new arrivals there this morning.

Be sure to come on back and let us know how it goes!

Good Birding

So a group of Franklin Township birders have started an owl survey given the recent sighting(s) of Short-eared Owls in the area.
Here’s the email I posted to Jerseybirds with details on the surveys…

Hey Jerseybirders:

Thanks to Jimmy Lee for finding the “closest Short-eared Owls to my house”
Because of this finding, the willing participation of local birders, and because for the last 4 years I’ve driven around Franklin TWP thinking “dang- there must be some good birds around here with all these fields!”, I’ve finally gotten around to setting up an Owl (or whatever you want to survey) survey. I’ve made a Google Map with some locations that I, or others in the area, have seen as good vantage points for searching for Shorties, and come up with a protocol for recording and reporting your observations.

The goal is simply to determine the number and spatial distribution of Short-eared Owls wintering in Franklin Township.

Here is a link to our datasheet:

And here is a link to the Google Map:

If you’d like to participate in these surveys, email me and I’ll add you as a collaborator on the map and data sheet, which will allow you to edit the survey points (map) and data (data sheet), rather than just view it.

This is a rogue citizen science project, with no oversight and no planned use for the data. Use of the data is at your own risk.

Survey Protocols

Before the survey:

- access the map and choose a survey location you will attend.
- choose “edit” to begin editing the map
- “edit” the survey location so you can add the DATE and YOUR NAME in the description for the point (see point ID SR 0001 for example).

What you’ll need to bring with you to the survey:

- a watch

- something to write with and on

- preferably a print-out of the map zoomed to your location so you can sketch your “field of view” (we can add this later to the google map which will give us a better idea of total coverage, and let us know where we might need to revisit to cover more area)

- binoculars

- spotting scope (optional)

- patience!

- Please DO NOT use any playback devices to attract owls (this creates a serious bias between surveyors and disrupts owls)

During the Survey:

- Be in position at your location 1/2 hour before sunset, and remain there for at least 1/2 hour after sunset.

- Choose a location that provides you maximum view, and record your “field of view” on your print-out

- Record the following: Time Start; Time Finished; Wind Direction and Strength (general idea is fine); Precipitation (if any); time of owl seen (for each owl seen); total number of owls seen during survey, for each owl record your “certainty” of identification (use percentages, and ask yourself “would you eat it”, based on the mushroom hunter’s motto- don’t eat it unless you’re 100% certain what it is! (from Lifebirds by George Levine)

- There is no systematic protocol, just scan the area casually during the survey period

After the survey
- When you get a chance, please email your survey result information to me (and/or the group) and (if you’re not opposed to Google Maps) please add a polygon on the map depicting your field of view.

- Add “completed” next to where you originally put the date and your name for your survey on the placemark. Eventually each placemark should have several dates with “completed” next to them, indicating replicated surveys at each point.

If you have any questions, please feel free to send them along.

There have also been some concerns about safety, so feel free to email the group and arrange to travel in pairs. One person could take one side of the road, while the other takes the alternate, or both can spread out over a field. Either way, don’t put yourself in harms way- and if you don’t feel comfortable, leave the scene! We can always go out there some other night. Carry a cellphone with you as well.

Adding Survey Points
As a collaborator you may add as many survey points to the map as you deem fit. Please follow the naming convention already established:
XX 000X –> the two letter abbreviation for the nearest road (Suydam Rd. = SR; Canal Rd. = CR, etc.) + a space + 000 + the number in sequence, following the last named point along that road (if we go into double-digits, then it will be two leading zeroes ie. 0010 is the 10th point in that series).
Please be conservative when adding survey points- and email the group so we’re aware of the new location.

Good Owling!

David
