Late surge of monarchs

Monarch numbers were good last week, but extreme winds kept most hunkered down over the weekend.  Strong northwest winds continued on Monday, and a noticeable increase of monarchs occurred.  Observations were made at Cape May Point, at the Avalon Seawatch, and at Stone Harbor Point.  Tuesday's weather forecast is very promising; if weather like this had come two or three weeks ago we would have predicted a very large flight of monarchs.  It's late in the season, so we don't expect a huge flight, but we do expect the numbers to increase over the next day or two.  We'll be out there watching, and at the very least we know there will be excellent flights of migratory birds occurring.

Here are a few photos from Monday.

Last tagging demos

It's been a week of steady monarch migration through Cape May, and our team has accomplished a lot of tagging.  The seaside goldenrod is at peak bloom along the dunes at Cape May Point, but surprisingly we haven't seen many monarchs here.  We've watched them taking off over Delaware Bay and heading to Mexico, but most of the nectaring monarchs have been seen in the local gardens.  Friday's forecast suggests another good day for seeing monarchs at Cape May Point, but high winds are predicted for the weekend, and those are not good conditions for monarch viewing.

Our education programs are wrapping up for the year.  Last Sunday we held the year's final tagging demo at Cape May Point State Park.  We are grateful for the hundreds of visitors who attended these programs.  On Wednesday we held our final Triangle Park drop-in program for 2016.  This weekend, both Saturday and Sunday, we'll offer short tagging demos at noon at the Cape May Convention Hall, part of the New Jersey Audubon Society's autumn festival, details here: NJA Fall Festival.

Our field studies continue until October 31, so if you're around Cape May Point watch for members of our team.  We're usually the only ones carrying butterfly nets.  We're always happy to greet visitors and talk about monarch butterflies.

Monarch numbers in Cape May Point have been steady for the last week or so, and we saw a modest increase yesterday.  While there's no great spectacle, there have been enough monarchs to keep our taggers busy.  Conditions look good for Thursday and Friday, and we're hoping that we will finally see a significant surge of migrant monarchs arriving into Cape May.  A big cold front is predicted to arrive for the weekend, however, with winds predicted to be from 20 to 40 mph, and those aren't good winds for monarchs.  Whatever the weather, we'll be continuing our censuses every day through October 31.

It's a great time of year to visit Cape May Point.

Will change in weather bring monarchs?

We had another heavy rain in Cape May over the weekend, but the rain cleared out on Sunday afternoon, pushed out by the autumn's first major cold front.  Gusty northwest winds triggered a major hawk flight, with hundreds of falcons passing over the Point on Sunday afternoon and a staggering tally of over 3,000 raptors counted on Monday.  Northwest winds are often the best for monarch migration too, but the winds were a bit too strong for a major butterfly migration event.

Tuesday is starting out clear and cool, with winds switching around to the northeast.  Could this be the day for a major influx of monarchs into Cape May?  It's certainly possible.  One of our volunteers reported a noticeable increase in monarchs yesterday at Ocean City, NJ, about 25 miles to our north.  Our team will be out watching today, and we'll report back promptly if monarch numbers increase significantly.

We saw a few more monarchs around Cape May during the first week of October, but the easterly winds that have dominated this autumn have continued, and the total monarch numbers remain low.  We're hoping that the east winds have pushed many migrating monarchs to the west side of Delaware Bay.  We hear encouraging reports about the numbers of monarchs being seen in Pennsylvania and further south, including reports from the Blue Ridge Mountains.  Monarchs will continue to migrate throughout the month of October, so we still have chances to experience a few big butterfly days.

While our counts are low, attendance at our various programs remains high.  Our tagging demos continue on Wednesdays, Fridays, Saturdays, and Sundays through October 16.  Meet our team at 2:00 pm for one of these talks, which are held at Cape May Point State Park's East Picnic Shelter.  Our informal drop-in programs at the Triangle Park continue through October 19, daily at 11:00 am.

A good Sunday, recoveries, request to taggers

Sunday, Oct. 2 brought a good flight of monarchs into Cape May Point.  While far from spectacular, it was certainly encouraging, since the entire month of September was very slow.  The good flight continued through Monday morning.

We have recovered several monarchs in recent days that were not tagged by our team, two each from tag sequences WPJ and WRC.  From replies to our Facebook posts we know that WPJ 369 and WPJ 370 were released here in Cape May by Danielle Pla.  We would love to know who tagged WRC 508 and WRC 512, plus when and where they were tagged.  When we find several in the same sequence it's usually someone who has been tagging here in Cape May.  We don't mind others tagging here, but we would greatly appreciate knowing that you're working here, and it would help us to know the tag numbers that you've used here.  We try to keep track of the total number of monarchs tagged in Cape May each year, and it's likely we'll recapture some; it helps us to know the ones that are from nearby.  We also advise visiting taggers to stay out of private property unless you're given express permission to enter, including yards where our team has been granted permission.

Sometimes people who have raised monarchs inside will drive down to Cape May Point to release these butterflies, thinking that they're giving them a head start.  Unless you live nearby, please don't do this!  Your butterflies will have a greater chance of success if you release them in the same area where they spent their lives as caterpillars, even if it's considerably north of Cape May.  Additionally, we have been conducting daily censuses of the monarchs in Cape May Point for over 25 years, and the accuracy of our data is diminished if extra monarchs are delivered to this region.  Please, please, don't bring monarchs from elsewhere into Cape May.

Many thanks!

Another foreign recovery

Thanks to Cape May visitor Marian Quinn for sharing this information and photo.  Please contact us if you have any information about when and where this monarch, WRC 508, was tagged, and by whom.  Many thanks!
