Nest Summary/Expected hatch dates:
Nest/Brood 1 - Cape Point. Four chicks hatched on 5/13. The four chicks are seven days old and should fledge sometime after 6/9.
Nest/Brood 2 - Cape Point. Two chicks hatched on 5/14 and are six days old and should fledge sometime after 6/10.
Nest 3 - Cape Point. This nest was discovered as a two-egg nest on 4/22, exclosed as a three-egg nest on 4/24, and was a four-egg nest on 4/27. Hatching should occur on or near 5/20.
Nest 4 - Cape Point. This nest was discovered as a two-egg nest on 4/22, exclosed as a three-egg nest on 4/24, and was a four-egg nest on 4/27. Hatching should occur on or near 5/20.
Nest 5 - Cape Point. This nest was discovered as a one-egg nest on 4/22, exclosed as a three-egg nest on 4/28, and was a four-egg nest on 4/30. Hatching should occur on or near 5/23.
Nest 6 - Cape Point. This nest was discovered as a two-egg nest on 4/22, exclosed as a four-egg nest on 4/27. Hatching should occur on or near 5/21.
Nest 7 - South Point. This nest was discovered as a one-egg nest on 4/28. On 5/2 the egg(s) were predated by ghost crabs. It is unknown whether the nest was a two-egg or three- egg clutch when predated.
Nest 8 - South Point. This nest was discovered as a one-egg nest on 4/28. Since the pair was incubating, the nest was exclosed as a two-egg nest on 5/2. One egg was predated by a ghost crab on 5/4. The one remaining egg was abandoned on 5/5 and predated by a ghost crab on 5/7.
Nest 9 - South Point. This nest was discovered as a one-egg nest on 5/4, exclosed as a three-egg nest on 5/8, and was a four egg nest on 5/12. Hatching should occur on or near 6/3.
Nest 10 - South Point. This nest was discovered as a three-egg nest on 5/16 and exclosed the same day. The nest is still a three egg nest as of 5/18. This nest is most likely a re-nest from pair #7, which laid Nest 7 on South Point. Hatching should occur on or before 6/11.
Nest 11 - South Point. This nest was discovered as a three-egg nest on 5/16 and exclosed the same day. The nest became a four-egg nest on 5/17. Hatching should occur on or near 6/11.
WIPL Update:
WIPLs have been observed on a regular basis on South Point Ocracoke within the pre-nesting closure. One nest, found as a 1 egg nest on 5/10, has been confirmed as a WIPL nest.
American Oystercatchers (AMOY): Pairs continue to be observed on scrape territories in all districts.

2010 AMOY Breeding Pairs: Twenty confirmed breeding pairs of AMOYs have been documented this year. One pair has re-nested after losing its three-egg clutch. Another one-egg nest at Cape Point, discussed below under Hatteras District, does not yet have an identified pair attributed to it. Five “potential” pairs, for which scraping and breeding have been observed, are being closely monitored. An additional “potential” pair is on Green Island, but we have not been able to access the island since 4/30 to conduct surveys.
Bodie District:
- Green Island: Surveys were not conducted this week.
- Bodie Island: A one-egg AMOY nest is being incubated. This nest is a clutch continuation and the first two eggs laid in different locations have been lost.
- Bodie/Hatteras District (Rodanthe to Ramp 30): Three breeding pairs have nests (two two-egg and one one-egg). The first two-egg nest should hatch on or near 5/21 and the second two-egg nest should hatch on or near 5/25. One pair has three chicks that hatched on 5/15 and 5/16.
Hatteras District: 7 breeding pairs have nests (five three-egg, one two-egg, one one-egg) and there are at least two more pairs are on scrape territories. Four nests have hatched (10 chicks), but a two-day-old chick appears to have been lost to unknown causes after hatching. At last observation the other two eggs in the nest were past due and had not hatched and a broken egg, with an under-developed embryo, was the only evidence at the site.
A pair for the one-egg nest has not been determined. An unbanded bird which was observed at the nest on 5/17 hasn’t returned and a banded bird, which has a three-egg nest with another banded bird, was observed on the nest. No birds were observed near the nest on the 5/19.
Ocracoke District:
- North Ocracoke: One pair is incubating a three-egg nest.
- Other Beaches (Ramp 59-Ramp 72): One breeding pair has three-egg nest. Another AMOY pair has documented breeding behavior, but no nest. The third pair hatched two chicks from a three-egg nest on 5/17. The third egg was pipped but never hatched.
- South Point: Two pairs of AMOYs are occupying the area south of Ramp 72. One pair is scraping on the east side of the pre-nesting closure. The other pair had lost two eggs due to weather (one on 4/29 and another on 5/2), but now is incubating a two egg nest (clutch-continuation) on the east side of South Point.

Bodie District:
Bodie Island: PIPLs have not been observed this week. No breeding activity was observed.
Hatteras District:
Cape Point: Up to 7 PIPLs have been observed at one time. Six pairs have nests. There is an active scrape territory, but it has not yet been determined if it is maintained by a paired male.
South Beach: Two lone male PIPL have been observed. Both are maintaining scrape territories.
Hatteras Overwash/Hatteras Inlet: No PIPL have been observed.
Other Beaches: One to two PIPL have been observed foraging at the ponds near Ramp 43.
Ocracoke District:
North Ocracoke: Up to five PIPLs have been observed foraging and/or roosting. Throughout the week PIPLs were observed on the oceanside and inlet shorelines, all within closures.
South Point: Up to six PIPLs have been observed along the inlet and oceanside shorelines, as well as within the mudflats. Three pairs have had documented nests. Two nests were lost and one four-egg nest remains.
A new one-egg nest was found on 5/10 but we are uncertain as to whether it is a Wilson’s plover or PIPL nest. As of 5/12 it was still a one-egg nest and no birds were observed in the vicinity of the nest to enable us to confirm species.

*Partial hatch. As of 5/12 one of three eggs in the clutch had hatched.
**This number differs from last week’s report due to a clutch continuation from an AMOY pair that lost the first two eggs of their clutch.
2010 AMOY Breeding Pairs: Twenty confirmed breeding pairs of AMOYs have been documented this year. One pair has re-nested after losing its three-egg clutch. Five “potential” pairs, for which scraping and breeding have been observed, are being closely monitored. An additional “potential” pair is on Green Island, but we have not been able to access the island since 4/30 to conduct surveys.
Bodie District:
- Green Island: Surveys were not conducted this week.
- Bodie Island: A one-egg AMOY re-nest was found on 5/11.
- Bodie/Hatteras District (Rodanthe to Ramp 30): Four breeding pairs have nests (two two-egg and two three-egg). The first nest should hatch on or near 5/14.
Hatteras District: 10 breeding pairs have nests (Seven three-egg, two two-egg, one hatching) and there are at least two more pairs are on scrape territories. The first nest of the year hatched on 5/12 (one chick and two pipped eggs in process of hatching) with incubation/brooding continuing at last observation.
Ocracoke District:
- North Ocracoke: Two pairs are occupying North Ocracoke. One pair has a three-egg nest. The other pair has documented scrapes around the area of Ramp 59.
- Other Beaches (Ramp 59-Ramp 72): Two breeding pairs have three-egg nests. The first nest should hatch on or around 5/14. A new AMOY pair was documented copulating and scraping on 5/9, 5/10, and 5/11. No nest has been documented for this pair yet.
- South Point: Two pairs of AMOYs are occupying the area south of Ramp 72. One pair is scraping on the east side of the pre-nesting closure. The other pair had lost two eggs due to weather (one on 4/29 and another on 5/2), but now is incubating a two egg nest (clutch-continuation) on the east side of South Point.
