Notes from the week

This week featured 5 school groups and two other non-school groups at Haystack Rock. Three groups  were on the beach on Friday which featured an Aquaria station. There were also 2 additional visiting groups on Saturday. The highest count on the beach was 130 on Friday, followed closely by 117 on Saturday and 124 on Sunday.

The Black Oystercatcher nest in the saddle has eggs and the oystercatchers have started swapping 'nest duty'. On Saturday, swaps occurred at 7:20, 8:10, 9:30, and 11:00. Neal Maine was in the intertidal trying to get a pictures of the eggs, but was unsuccessful ... this time!

A harbor seal pup was spotted amongst the boulders on the south side of Haystack Rock. Mothers will leave their pups on shore while they are out foraging for food, then will come back for them. It is important for people to not disturb the pups and keep at least 50 feet away, which is the law under the Marine Mammal Protection Act. The mother will not return if there are people present. During Monday's shift, HRAP staff and volunteers monitored the pup and using signs attempted to keep the public at a safe distance. They stayed after the shift finished to continue monitoring the pup.

Creature Highlights

Birds

  • Black Oystercatchers (Haematopus bachmani) - Black oystercatcher still on their nest in the saddle.
  • Bald Eagle (Haliaeetus leucocephalus) - Bald eagles, adults and juveniles, again made multiple appearances this week. 
  • Wandering tattler (Heteroscelus incanus) - Uncommon in Cannon Beach except during migration. This individual may still be migrating north or decide to forgo the journey this year and spend the summer here. See details on the Wandering tattler here.
Fish

  • Kelp Greenling (Hexagrammos decagrammus) - a male greenling was spotted

Invertebrates
  • Frosted Nudibranch (Dirona albolineata) - Normally about 1 1/2 inches, thy live on rocky shores and the low intertidal to a water depth of 100 feet. They are opaque, with projections that are edged with a fine brilliant white lien. They feed on small snails, sea anemones, sea squirts, and bryozoans. 
  • Shaggy Mouse Nudibranch (Aeolid papillosa) - Spotted on a north boulder with eggs
  • Rufus Tipped Nudibranch (Acanthodoris nanaimoensis)
  • Leopard Nudibranch (Diaulula sandiegensis)
  • Pygmy Sea Cucumbers
  • Hermit crab - spotted molting on Sunday
  • Smooth Bay Shrimp (Crangon stylirostris) - A common species in the tide pool that buries itself in the sand. A lot of visitors stumble upon these when they are running their hands through or digging in the sand. They usually quickly rebury themselves.
Mammals
  • Harbor Seal (Phoca vitulina) - Very small seal pup was spotted between the large boulders on the south side. The pup was sleeping and seemed unaware of the people in the intertidal
