Overall, we have 35 pairs, 11 singles, 4 active nests, 48 chicks, and 5 fledglings!
Last week, we had dense fog during one of our surveys, so I know some birds were not seen, but were still around.

It seems like birds are starting to move around as the breeding season wraps up. Some birds have moved on, while we are seeing new birds move through the area, using our beach as a stopover.
Our new least tern colony was surveyed last week, resulting in a high count of 67 adults.
Friday, July 5, 2019
As of this week have a total of 84 adults (41 pairs, 2 singles), 3 fledglings, 63 chicks, and 9 nests!
After today's survey I don't think all chicks were seen; I believe we could have closer to 70 chicks. Some pairs are also inconsistently being observed. I even think there are still a few nests to be found, but they are likely in thick vegetation and are difficult to search for.
Over the next week to week and a half, more chicks should be fledging!
Our first least tern chick was also spotted this week! It was able to walk around and even looked like it had some pin feathers. In addition to our main least tern colony (which contains at least 50 adults), more least tern adults were observed staging and foraging from mm 0.1 through at least mm 1.0, but I was not able to get a high count across this transect. I will keep an eye on these birds to see if they attempt to nest.
A BIG thank you to our amazing plover wardens, outdoor rec. and visitor services staff, and Gareth for working super hard over the course of this busy and hot holiday week to protect our beach and birds!

As of last week, we currently have a total of 125 piping plovers on the refuge beach! This includes, 36 pairs, 6 single plovers, and 47 chicks. It's very likely we have more chicks on the beach, but full broods were not detected in some cases. I believe unsuccessful nesting pairs are beginning to leave their territories and move freely around the beach, or even to a different beach, since they haven't been seen for several surveys and groups of non-territorial foraging birds have been observed.
There are currently 13 active nests. I believe there is still a few pairs that are attempting to nest one, or have a nest to be found.
Furthermore, there was a high count of 50 least terns seen in the colony. No chicks observed yet.
Big thanks to intern Jesse and biologist Nancy for covering nest checks and surveying in the latter half of last week!

In total, we have 45 pairs (90 adults), 22 nests, and 39 chicks! We have many more hatches to come and our first fledge date is slated for Thursday 6/27. At this point in the season, I believe some unsuccessful pairs are moving on, for I have not seen them, or signs of their presence, for at least several surveys.

Within the least tern colony, 12 nests have been found, meaning we have at least 24 adults. However, we believe there to be more adults! Unfortunately, clouds and occasional fog did not provide the best counting conditions.

In total, 90 birds were observed (44 pairs and two single plovers). There were 26 active nests, and 10 chicks were spotted on the beach!

By the end of this week you'll get another update from me pertaining to this week's numbers. As long as everything goes as planned, the numbers should look really good!

After two very thorough surveys, I have observed 44 pairs on the beach, along with two single plovers whom I'm not quite positive if they have a mate. These numbers put our population at 90 TOTAL PLOVERS. Wow, that's a lot...

Overall, we have 32 nests! This means almost all pairs currently have an active nest.

This week also saw the hatching of our first nest! Three chicks were seen running around just north of Boardwalk 7 on Friday. So far, so good for this brood. With the high foot traffic on Sandy Point, and our newfound piping plover family in this area, please be even more aware of trespassers entering the south boundary.

LETE tern nesting is also well on it's way. There are at least 45 pairs within the colony. Several one egg and two egg nests have also been found. Within the next week or two, an official census will be conducted.

This week has been fairly productive- for the plovers and myself! There are 39 pairs, and one single plover- totaling 79 birds.
Overall, there are 25 active nests on the beach! Like most weeks, there were some losses, but with many new finds. At least this week more nests were found than lost.
I kept my eye out for chicks today, but alas we still only have eggs. My earliest predicted hatch date is June 6th, but I wouldn't be surprised if chicks start showing up sooner.
Although no least tern nests have been found yet, they are acting a lot more aggressive! Hopefully nests will appear starting next week. I better start bringing out a large sunhat!

'This week has been a good one for our plovers! There are a total of 20 nests. More nests are found every time I go on the beach, and I have a feeling there are still a few I haven't found yet. In total, we have 79 piping plovers (39 pairs, 1 single).
Most birds have bounced back very quickly after their nest was depredated or flooded last week. By the first week of June there may even be some chicks running around!
Least terns have also begun to colonize and scrape!'

'As of yesterday, we have 29 pairs and five single plovers- totaling 63 adults! Birds are certainly settling down now, but they are also still popping up in new locations.
There are also nine active nests on the beach! Five of the nine nests have four eggs, and are being fully incubated.
Soon enough, least terns should also be settling down on the refuge beach!'

'This week we had a total of 63 piping plovers (30 pairs, 3 singles). Our first nest was found on Wednesday with one egg! As of Friday 5/3, the nest has 2 eggs.

Overall, birds are settling and there is still a lot of scraping activity. On the other hand, we also have birds that are still passing through.'

'This week, 18 pairs and 4 single plovers were observed on the refuge beach, totaling 40 adults! Unlike previous surveys, no larger (likely migratory) groups were seen this week; plovers were only observed as pairs or single.
Once again, a lot of scraping activity was noted. I checked on scrapes found last week, but a number of them were washed out. Fortunately, the plovers have been busy creating new scrapes to try out! While no eggs were found, birds are still actively maintaining territories, courting, and are weary of intruders.
Most territories did have coyote tracks going through them. Thankfully, no trespassers or human prints were detected on the beach during this survey.'

'On the April 17th plover survey, 22 pairs were observed, along with a lot of nesting activity! 10 lone plovers were also observed this past week. In total, 54 adult Piping Plovers were counted.
Despite the falling tide and abundance of foraging area, a lot of birds were sticking close to the wrack line, or, if they were closer to the shoreline, would walk back towards the dune relatively quickly. Several males were also seen establishing territory lines. This behavior is indicative of the plovers becoming weary of intruders and more attached to their potential nesting territories.
For almost every pair, one (or several) scrapes were found. Several birds were seen testing out their scrapes. One pair was even seen courting and copulating! Needless to say, our plover tech is excited for next week's survey.'

'On Thursday, 45 adult Piping Plovers were detected on the refuge beach! Birds were observed at a lot of the same locations as last week. Additionally, where lone adults were seen last week, pairs were present this week. In total, there were nine distinctive pairs observed.

While there are more pairs being seen, in consistent locations, it's very likely birds are still migrating north. In addition to the nine observed pairs, larger flocks of piping plovers were observed in groups of four, five, six, and ten individuals! Only two individuals were solo (not among a pair or large group).

This survey was conducted at low tide; therefore, all birds observed
were taking advantage of the wide beach and foraging along the
shoreline. Furthermore, heavier sets of tracks were being detected
between the shoreline and the dunes. Because of this, next week I'll
start looking for scrapes and keying in on territorial behavior.

Aside from piping plovers, a large mixed flock of shorebirds was
foraging and cleaning themselves at the shoreline in front of Lot 7.
This flock consisted primarily of semipalmated sandpipers and
sanderlings, totaling over 200 individuals.'
