Can Ducks See Color?

Because waterfowl have a high number of cones — which dictate color vision in humans — they have color vision where colors are more vivid than what humans have the ability to see (Wood duck photo courtesy of U.S. Fish and Wildlife Service)

Question: Can ducks see color? I know deer see different shades of gray, but what about ducks and geese? (David V.)

Answer: Well, this actually is a fairly entertaining question since waterfowl are much different than many other animals — especially us!

According to Department of Fish and Game (DFG) waterfowl biologist Shaun Oldenburger, waterfowl can control the curvature of both the lens and cornea (mammals, including humans, only control the lens). This is basically how birds can see extremely well while flying and while in the act of diving/feeding. In addition, their eyes act independently and they use one at a time to allow for depth-perception since nearly all waterfowl have monocular, not binocular, vision (they can’t stare forward at objects).

Another unique thing about waterfowl is they can see in almost all directions. A few ducks are the exception to the rule, but usually the eye placement allows them to view in many different directions at the same time. Secondly, waterfowl have a very high number of cones (which dictates color vision in humans) which allows them to see sharp images and have color vision where colors are more vivid than humans’ ability. The breadth of color vision is much wider than our own since UV light can be observed by waterfowl (UV light is absorbed by lenses in humans). This allows waterfowl to fly at night or feed in the dark or at low light conditions.


Are pier anglers considered shore-based anglers?
Question: I know that rockfish, lingcod and all groundfish are open year round to shore-based anglers. Does that include pier anglers? Seems to me that piers are shore-based, but thought I’d best check to be sure since I don’t see it spelled out in the regs. (David B.)

Answer: Yes, pier anglers are considered shore-based anglers.


Hunting deer after dropping their antlers?
Question: I have a question about a deer being legal to take after it drops its antlers. I hunt during the late archery deer season and was hunting one buck for about a month. By the end of the A-22 archery season, the buck had dropped both antlers. The regs read as follows:

§351. Forked-Horn Buck, Antlerless and Either-Sex Deer Defined.

  • (a) Forked-Horn Buck Defined. For the purpose of these regulations a forked-horn buck is defined as a male deer having a branched antler on either side with the branch in the upper two-thirds of the antler. Eyeguards or other bony projections on the lower one-third of the antler shall not be considered as points or branches.
  • (b) Antlerless Deer Defined. For the purpose of these regulations, antlerless deer are defined as female deer, fawns of either sex other than spotted fawns, and male deer with an unbranched antler on one or both sides which is not more than three inches in length.
  • (c) Either-Sex Deer Defined. For the purpose of these regulations, either-sex deer are defined as antlerless deer as described in section 351 (b), or legal bucks that have two or more points in the upper two-thirds of either antler. Spike bucks may not be taken.

The way I read the regs, it would be illegal to shoot a buck after it dropped its antlers. Can you clarify this for me please? (Jim P.)

Answer: Yes, you are correct. That deer got lucky this year!


Lifetime licenses?
Question: Why did California stop sending lifetime licenses out? At the time of purchase there were no restrictions implying I had to remain a resident of California and I had no intentions of moving. Circumstances changed though and now I live out of state. Does this negate the lifetime license privileges that I’ve already paid for? (Aron H., Homer, Alaska)

Answer:  No, your lifetime license status has not changed because you moved out of state. According to DFG Sport Fishing/Waterfowl/Upland Game Program Analyst Glenn Underwood, a change in lifetime license issuance procedures was made when we launched the Automated License Data System in 2010.  Lifetime license customers must now verify that their personal information is correct and request their license annually.

There are three ways to claim your license:

1. Pick up your license at any license agent. A list of license agents is available at www.ca.wildlifelicense.com/internetsales/OutletSearch/FindOutlet.

2. Order it online at www.dfg.ca.gov/licensing. Log in and complete your transaction as though you are making a purchase. There will be no charge for your lifetime license.

3. Call (800) 565-1458 and your license will be mailed to you.

History of the Tejon Ranch Elk?

Rocky Mt. elk from Yellowstone National Park were imported into California in 1966 and released in Kern County (U.S.F.W.S. photo)

Question: I live in Stallion Springs, a rural community about 15 miles west of Tehachapi, and we have bands of elk that roam in the neighborhood. They move freely between the adjoining huge Tejon Ranch and the neighboring Bear Valley Springs community. I have been told by a born-and-raised Tehachapi native that the elk escaped in the early 1970s from a high fence operation located in the nearby Cummings Valley. Are they Rocky Mountain Elk or the Roosevelt subspecies? How does the Tejon Ranch conduct hunts for these elk when we never see anything in the hunting regulations about this? And, since their rutting season usually runs from late October into November in other areas, why do these animals go into the rut from the end of August to the very beginning of October? Furthermore, deer hunt zone D10 is all on private land and that zone is open to draw. Thanks for any light you can shed on these questions. (Ron A., Stallion Springs)

Answer:In 1966, the Department of Fish and Game (DFG) issued a permit for the release of 300 Rocky Mountain Elk imported from Yellowstone National Park into a fenced compound on a game farm ranch in southern Kern County. By 1967, 290 elk had been shipped from Yellowstone, but due to the stress of transport and possibly other causes, only 277 survived to be released inside the ranch enclosure. Many elk died within the enclosure from several diseases brought on by stress induced by confinement, as well as a new and different diet. Later that year elk began escaping because of the lack of fence maintenance. It is not known exactly how many animals escaped to the wild (California Fish and Game, 61(4):239-241. 1975).

According to DFG’s Elk and Pronghorn Coordinator, Joe Hobbs, approximately 200 animals currently reside in this area in an around the Tejon Ranch. Elk game farming is no longer allowed in California. The Tejon Ranch runs their elk hunting through the DFG’s Private Lands Management Program (PLM). In exchange for conducting habitat improvement projects on their land that benefit wildlife, landowners can receive special PLM elk tags each year. The numbers and types of tags correspond to the population level of elk and the current conditions on the ranch. Elk in this area may have an earlier rutting season due to the warmer weather in Southern California.


Are crabs with black spots safe to eat?
Question: I just bought two crabs and found one with black spots on the outside shell. I’ve seen these before and usually avoid them, but this time the seller sneaked it into my package. When I called him about it, he said he didn’t know what it is, but it doesn’t permeate the shell. This isn’t true—I’ve seen this stuff on the flesh at the joints. It looks like oil. Can you enlighten me? Besides being ugly, is it unsafe? (Mari V., Berkeley)

Answer: According to our senior fish pathologist Jim Moore, black spots on the shells of crustaceans are typically composed of melanin, which is the end product of a series of immunological reactions. This means the crab was likely responding to some shell damage that could be caused by physical trauma or a disease agent. In this case, the black spotted crab is probably safe if cooked correctly. However, if the discolored shellfish tissue has an unpleasant taste or texture, or looks or smells unusual, we always recommend not eating it.


Concealed weapon law when hunting/fishing
Question: I have a question about carrying a concealed weapon (pistol/revolver) while engaged in hunting/fishing in California without a CCW permit. My understanding of Penal Code 12027 is that if I’m engaged in hunting/fishing, I can carry a loaded concealed weapon, but when en route to and from, I need to unload the firearm but it may be concealed. (David F., Lake Almanor)

Answer: This is correct. Licensed hunters or fishermen can carry loaded and concealed pistols, revolvers or other firearms capable of being concealed upon their person while engaged in hunting or fishing as long as they are in a place where it is lawful to carry a firearm. When going to or returning from the hunting or fishing expedition, or when transporting those firearms, they must be unloaded (PC, section 12027(g)).

This exemption does not apply in all cases though. While handguns may be used to take certain types of game in the field, the carrying of a loaded handgun while fishing from a public place in an incorporated city, or in prohibited areas outside of incorporated cities could constitute a violation of PC 12031(a)1). It is also not lawful, to carry a concealed firearm, or any firearm at all, when hunting under an archery only tag or during an archery only season.


Disposing of unwanted shotgun shells
Question: Where can I dispose of old unwanted shotgun shells and rusted bullets? (Frank G.)

Answer: Check with your local Police or Sheriff’s department. DFG has no laws or regulations regarding disposal of unwanted ammunition.

Releasing Sea Creatures Back to the Wild?

DFG photo

Question: Instead of taking life by the act of fishing or eating sea creatures, I want to save the lives of those creatures from seafood markets that are about to be killed for food by buying them and releasing them back to the ocean. Please let me know what kind of live sea creatures (crabs, oyster, shrimp, fish, etc.) are allowed to be legally released back to the ocean. I don’t want to do anything illegal, so please let me know of any restrictions I may need to know. (Justin)

Answer: Unfortunately, it is illegal to release any ocean finfish or shellfish from captivity back into ocean waters (Fish and Game Code, section 6400). Animals living in a fish tank or captive environment may have been exposed to foreign diseases and/or parasites and now carry them. To protect the natural ocean environments and prevent captive finfish and invertebrates from introducing these foreign diseases and/or parasites to healthy wild stocks, it is illegal to move or reintroduce them to the wild.


Shooting a nuisance bear?
Question: I have a buddy who lives near Lake Arrowhead. They have a bear that has been vandalizing their property (like getting into trash cans), threatening animals and making them on edge at night or during the day. Would it be legal to shoot this nuisance animal? (Joey Cox, Tulare)

Answer: No, it is not legal to take this or any bear unless you are a holder of a valid bear tag during the open season or are a person operating under the conditions of a valid Depredation Permit issued by the Department of Fish and Game (DFG).

Tell your buddy to contact DFG in Southern California at (909) 484-0167 to report the damage being caused by the bear and to obtain information about the requirements for acquiring a depredation permit.


Where to stick a stamp?
Question: I just bought the new California computerized hunting license. Since it is issued by the state, Big 5 sold me the federal waterfowl stamp separately. The federal stamp is not printed on the license. Where do I stick it on the license since there is no place designated like the past licenses? Also, if a person buys the initial license with no stamps, then decides to duck hunt later, how do they add the printed stamp info? Do you have to pay for a new license over again? (Anonymous)

Answer: The law does not require the federal waterfowl stamp to be attached to the new license. You just need to have it in your possession while hunting (along with your license) so you can present it to a game warden upon request. You may want to just staple it to your hunting license to keep them together. The federal stamp must still be signed no matter where it is kept. If a person buys a license and later wants to get validations for bird hunting, they will be given an additional printout of the validations and must carry that along with the original license.


Big Game hunting with an airgun?
Question: Is it legal to hunt and take big game in California with an airgun of any caliber? I am aware that small game (rabbits, squirrels, etc) may be taken with any caliber airgun and turkeys may be taken with a .20 caliber or larger airgun. I read this question recently on a very widely viewed airgun forum. (Mike Clark)

Answer: Air rifles are unlawful for this purpose. Check California Code of Regulations Title 14, section 353 for the specific methods allowed for the taking of big game.


How fast do abalone grow?
Question: How fast do abalone grow?

Answer. Abalone are relatively slow growing. Tagging studies indicate northern California red abalone take about 12 years to reach seven inches, but growth rates are highly variable. Abalone grow nearly one inch per year for the first few years, and much slower after that. It takes about five years for red abalone to grow from seven inches to eight inches. At eight inches, growth rates are so slow it takes about 13 years to grow another inch. Slow growth makes abalone populations vulnerable to overfishing since many years are needed to replace each abalone taken.
